4x - 5(3x + 10) = 126
4x - 15x - 50 = 126
4x - 15x = 126 +50
-11x = 176
x = 176/(-11)
x=-16 <---------------- Answer

4x - 5(3x + 10) = 126
4x - 15x - 50 = 126
Simplify the left side:
-11x - 50 = 126
Add 50 to both sides:
-11x = 176
Divide both sides by -11 to get:
x = -16

4x-5(3x+10)=126
4x-15x-50=126
add 50 and combine like quanities
-11x=176
divide by -11
x=-16
