Step-by-step explanation:

Step 1: Define

6x + 7y = 4x + 4y

y = -4

Step 2: Solve for x

1. Substitute:                               6x + 7(-4) = 4x + 4(-7)
2. Multiply:                                   6x - 28 = 4x - 28
3. Add 28 on both sides:            6x = 4x
4. Subtract 4x on both sides:     2x = 0
5. Divide both sides by 2:           x = 0
