Question

I.Solve the following.

1) 7r + 7 = 13 + 6r

2) 3 - 4x = 1 - x

3) -7x - 3x + 2 = -8x - 8

4) -14 + 6b + 7 - 2b = 1 + 5b

5) -6x - 20 = -2x + 4(1 - 3x)

6) 4n - 40 = 7(-2n + 2)

7) -31 - 4x = -5 - 5(1 + 5x)

8) -3(x - 1) + 8(x - 3) = 6x + 7 - 5x

9) 4(-8x + 5) = -32x - 26

10) (1/2)(8y - 6) = 5y - (y + 3)​
