Complete the steps to solve this linear equation: 2x + 9(x – 1) = 8(2x + 2) – 5
1.apply the distributive property: 2x + 9x– 9 = 16x + 16 – 5
2.combine like terms on each side: 11x – 9 = 16x + 11
3.use the subtraction property of equality to isolate the variable term: –9 = 5x + 11
use the subtraction property of equality to isolate the constant: –20 = 5x
4. use the division property of equality to solve: = x
