6x-10x-40=14+2x
Use the distributive property to multiply -5 by 2x+8.
-4x-40=14+2x
Combine 6x and -10x to get -4x.
-4x-40-2x=14
Subtract 2x from both sides.
-6x-40=14
Combine -4x and -2x to get -6x.
-6x=14+40
Add 40 to both sides.
-6x=54
Add 14 and 40 to get 54.
x=\frac{54}{-6}
Divide both sides by -6.
x=-9
Divide 54 by -6 to get -9.
