Solve each equation and show the steps you followed.
1.) -50 = -2(a + 3)
2.) 4 (x - 2) = 2(x - 4) + 2x
3.) 5(y - 2) - 2. = 2(y + 1) - 5
4.) -4(p + 1) = 2(8 - 2p)

1.) -50 = -2(a + 3)

-50 = -2a - 6

-50  + 6 = -2a

-44 = - 2a

a = 22

2.) 4 (x - 2) = 2(x - 4) + 2x

4x - 8 = 2x - 8 + 2x

4x - 8 = 4x - 8

0 = 0

All real numbers

3.) 5(y - 2) - 2. = 2(y + 1) - 5

5y - 10 - 2 = 2y + 2 - 5

5y - 12 = 2y - 3

3y = 9

y = 3

4.) -4(p + 1) = 2(8 - 2p)

-4p - 4 = 16 - 4p

     - 4 ≠ 16
