O Combine like terms on each side of the equation.
O Use the distributive property on each side of the equation.
Use the subtraction property of equality to subtract 5 from each side of the equation.
Use the addition property of equality to add 2x to each side of the equation.

Answer:

Your answer would be to Use the distributive property on each side of the equation.

Explanation:

You would first expand the equation by using the distributive property on each side of the equation


2x + 9(x - 1) = 8(2x + 2) - 5\\2x + 9(x) 9(-1) = 8(2x) 8(2) - 5\\2x + 9x-9 = 16x+16 - 5

Then you would combine like terms on both sides


2x+9x-9=11x-9\\16x+16-5=16x+11

Now you solve for x


11x-9=16x+11

You subtract 11x from both sides


11x-9=16x+11\\-11x=-11x

Then you subtract 11 from both sides


-9=5x+11\\-11=-11

Then you divide 5 on both sides


-20=5x


(-20)/(5) =(5x)/(5)


x=-4
