Answer 2

Step-by-step explanation:

7i)x + 7 + 4(x - 5)

x + 11(x - 5)

x + 11 × x - 5

2x + 6

7ii)3(x +2) + 5x - 7

3x +6 +5x - 7

8x - 1

7iii)6x + 5(x - 2)

6x + 5x - 10

11x - 10

7iv)4(2x - 1) + 3x + 11

8x - 4 + 3x + 11

11x + 7

8i)2a - 2b - 4 - 5 + a

3a - 2b - 9

8ii)2(a² + ab)+ 3 - ab

2a² + 2ab +3 - ab

2a² + ab + 3
