Question

12x - 20 = 15x - 38

Explanation:

Step1: Subtract \(12x\) from both sides

\(12x - 20 - 12x = 15x - 38 - 12x\)
Simplify to get: \(-20 = 3x - 38\)

Step2: Add 38 to both sides

\(-20 + 38 = 3x - 38 + 38\)
Simplify to get: \(18 = 3x\)

Step3: Divide both sides by 3

\(\frac{18}{3} = \frac{3x}{3}\)
Simplify to get: \(6 = x\)

Answer:

\(x = 6\)
