TLDRIn this 'Math with Mr. J' video, the host explains how to solve one-step equations by performing the inverse operation to isolate the variable. Six problems are demonstrated, illustrating the process of undoing subtraction or division to find the variable's value. The importance of balancing the equation by applying the same operation to both sides is emphasized, and each solution is verified for accuracy.

### Takeaways

- π To solve one-step equations, perform the inverse operation of what is done to the variable to isolate it.
- π The main goal in solving equations is to get the variable by itself on one side of the equation.
- β For subtraction in the equation, the inverse operation is addition.
- β When the variable is divided by a number, the inverse operation is multiplication by that number.
- π’ In the first example, adding six to both sides of the equation X - 6 = 13 results in X = 19.
- π§© For the second problem, multiplying both sides of K / 8 = 2 by 8 gives K = 16.
- π In the third example, subtracting 3 from both sides of the equation 3 + G = 16 leads to G = 13.
- π In the fourth example, dividing both sides of 15 = 5M by 5 results in M = 3.
- π For the fifth problem, dividing both sides of 2R = 22 by 2 gives R = 11.
- π In the sixth example, multiplying both sides of 11 = W / 4 by 4 results in W = 44.
- π Remember to always double-check your solution by substituting the found value back into the original equation to ensure correctness.

### Outlines

### π Solving One-Step Equations Introduction

This paragraph introduces a math tutorial by Mr. J focusing on solving one-step equations. Six problems are presented on the screen, and the key concept emphasized is performing the inverse operation to isolate the variable. The tutorial explains that inverse operations involve doing the opposite of what is done to the variable, such as adding when there is subtraction and multiplying when there is division. The first problem, X minus six, is used as an example to demonstrate the process of isolating the variable by adding six to both sides of the equation, resulting in X equals 19. The solution is verified by substituting the value back into the original equation.

### π Detailed Walkthrough of Solving One-Step Equations

The second paragraph continues the tutorial by solving additional one-step equations. It covers various operations including division, multiplication, and addition. For each equation, the inverse operation is identified and applied to both sides to isolate the variable. For instance, the equation K divided by 8 equals 2 is solved by multiplying both sides by 8, yielding K equals 16. The tutorial also includes a step-by-step solution for equations involving multiplication, such as 2R equals 22, solved by dividing both sides by 2 to get R equals 11. Each solution is verified by substituting the variable's value back into the original equation to confirm its correctness. The final equation, 11 equals W divided by 4, is solved by multiplying both sides by 4 to find W equals 44, which is also verified for accuracy.
