-11x-77+639=11+12
Use the distributive property to multiply -11 by x+7.
-11x+562=11+12
Add -77 and 639 to get 562.
-11x+562=23
Add 11 and 12 to get 23.
-11x=23-562
Subtract 562 from both sides.
-11x=-539
Subtract 562 from 23 to get -539.
x=\frac{-539}{-11}
Divide both sides by -11.
x=49
Divide -539 by -11 to get 49.
