x = - 4
Step-by-step explanation:
2x+4 (2x+7) = 3 (2x+4)
2x + 8x + 28 = 6x + 12
10x + 28 = 6x + 12
4x = - 16
x = - 4

x = - 4
Step-by-step explanation:
2x+4 (2x+7) = 3 (2x+4)
Distribute
2x+8x + 28 = 6x + 12
Combine like terms
10x + 28 = 6x + 12
Subtract 6x from each side
10-6x+28 = 6x + 12 - 6x
4x + 28 = 12
Subtract 28 from each side
4x+28-28 = 12-28
4x = - 16
Divide each side by 4
4x/4 = - 16/4
x = - 4
