Question

Which value of x makes the following equation true?

3(x - 4) - 12 = 2(x - 6) + 5

Answer 1

x = 17

Explanation:

3(x - 4) - 12 = 2(x - 6) + 5

3x - 12 - 12 = 2x - 12 + 5

3x - 24 = 2x - 7

3x - 2x = -7 + 24

x = 17

Answer 2

x=17

Explanation:

3(x - 4) - 12 = 2(x - 6) + 5

Distribute

3x -12 -12 =2x-12 +5

Combine like terms

3x-24 = 2x -7

Subtract 2x from each side

3x-2x -24 =2x-2x-7

x-24 = -7

Add 24 from each side

x-24+24 = -7+24

x = 17
