x
Consider the sequence of steps to sotve the equation: 3(% - 4) + 5x = 9X - 38
Given =3 3(x - 4) + 5x = 9x - 38
Step = 3X - 12 + 5x = 9x - 36
Step 2 - 3x + 5x - 12 = 9x - 36
Step 3 - 8x - 12 = 9% - 36
Step 4 = 8x - 8x - 12 = 9x - 8x -36
Step 5 = 0 - 12 = x- 36
Step 6- -12 = x - 36
Step 7- -12 + 36 =x - 36 + 36
Step 8 -> 24 = x + 0
Step 9 - 24 = x
