3x-4=8\left(x+2\right)
Variable x cannot be equal to -2 since division by zero is not defined. Multiply both sides of the equation by x+2.
3x-4=8x+16
Use the distributive property to multiply 8 by x+2.
3x-4-8x=16
Subtract 8x from both sides.
-5x-4=16
Combine 3x and -8x to get -5x.
-5x=16+4
Add 4 to both sides.
-5x=20
Add 16 and 4 to get 20.
x=\frac{20}{-5}
Divide both sides by -5.
x=-4
Divide 20 by -5 to get -4.
