Math Problem Statement

Solve the equation -2y + 6 = -12.

Solution

The equation provided in the image is:

2y+6=12-2y + 6 = -12

Let's solve it step by step:

Step 1: Isolate the term with yy

Subtract 6 from both sides: 2y=126-2y = -12 - 6

Simplify: 2y=18-2y = -18

Step 2: Solve for yy

Divide both sides by 2-2: y=182y = \frac{-18}{-2}

Simplify: y=9y = 9

Final Answer:

y=9y = 9

Would you like further clarification or explanation?

  1. What happens if you divide by a negative number in an equation?
  2. How do you verify that y=9y = 9 is correct in this equation?
  3. What if the equation had a fraction instead of 2y-2y?
  4. How can you rearrange terms in equations like this without confusion?
  5. How is solving multi-step equations different from simple equations?

Tip:

Always double-check your solution by substituting the value of the variable back into the original equation to verify correctness.
