Solve each equation:
serious [3.7K]

Step-by-step explanation:

1) -7 (divide -28 by 4 to isolate x)

2) -8 (two negatives = a positive, so it's x + 6 = -2, then subtract 6 from both sides)

3) 5 (subtract 4 from both sides, and multiply each side by -1)

4) 2 (subtract 7 from both sides, then divide by -3)

5) -3 (add 11 to both sides then divide by 25)
