Question

I really need help I have no idea

Answer 1

Step-by-step explanation:

1) - (7x - 8)= 2-5x

- 7x +8 = 2- 5x

- 7x + 5x = 2 - 8

- 2x = - 6

x = 3

2) 5(3 + 2x) = 10x - 4

15 + 10x = 10x - 4

15 +4 = 10x - 10x

No solution

3) x +5 = 3x + 13 /2

2(x +5) = 3x + 13

2x + 10 = 3x + 13

2x - 3x = 13 - 10

- x = 3

x = - 3

4) 2 + 6x =2(3x + 2) - 2

2 + 6x = 6x + 4 - 2

6x - 6x = 2-2

No solution
