Math Problem Statement

(2 - 3x) / 4 = 5

Solution

The equation you provided is:

23x4=5\frac{2 - 3x}{4} = 5

Let's solve it step by step:

Step 1: Eliminate the denominator

Multiply both sides of the equation by 4 to get rid of the denominator: 23x=5×42 - 3x = 5 \times 4 23x=202 - 3x = 20

Step 2: Isolate the variable term

Subtract 2 from both sides: 3x=202-3x = 20 - 2 3x=18-3x = 18

Step 3: Solve for xx

Divide both sides by -3: x=183x = \frac{18}{-3} x=6x = -6

Thus, the solution is: x=6x = -6

Would you like any additional details on these steps or explanations? Here are five related questions that could extend this problem:

  1. How would the solution change if the denominator were a different number, say 5?
  2. Can you solve for xx if the equation is 23x4=5\frac{2 - 3x}{4} = -5?
  3. What happens if you add a constant to both sides of the equation before solving?
  4. Can you create a similar equation but with a quadratic expression in the numerator?
  5. How would you approach solving the equation if the fraction included a variable in the denominator as well?

Tip:

When solving linear equations, always try to first eliminate fractions by multiplying both sides by the denominator to simplify the equation.
