-16x+40+3x=4\left(x+7\right)-10
Use the distributive property to multiply -8 by 2x-5.
-13x+40=4\left(x+7\right)-10
Combine -16x and 3x to get -13x.
-13x+40=4x+28-10
Use the distributive property to multiply 4 by x+7.
-13x+40=4x+18
Subtract 10 from 28 to get 18.
-13x+40-4x=18
Subtract 4x from both sides.
-17x+40=18
Combine -13x and -4x to get -17x.
-17x=18-40
Subtract 40 from both sides.
-17x=-22
Subtract 40 from 18 to get -22.
x=\frac{-22}{-17}
Divide both sides by -17.
x=\frac{22}{17}
Fraction \frac{-22}{-17} can be simplified to \frac{22}{17} by removing the negative sign from both the numerator and the denominator.
