Question

Solve the equation.
3(4x - 3) - 19 = 8x - 4

Answer 1

multiply through and subtract like terms

Answer 2

3(4x - 3) - 19 = 8x - 4 distribute
12x - 9 - 19 = 8x - 4 combine like terms
12x - 28 = 8x - 4 add four to both sides
12x - 24 = 8x subtract 12x from both sides
-24 = -4x divide by -4
6 = x

Answer 3

3(4x - 3) - 19 = 8x - 4
12x-9 -19 = 8x-4
12x - 28 = 8x-4
12x-8x = -4 + 28
4x = 24
x = 24/4
x = 6
