ax + b = cx + d (medium)

4 visual steps / collect x terms

1. Gather x

6x - 8 = 2x + 20Balance both sides. left side right side = 6x - 82x + 204x = 28x = _
Put x terms on one side.

Put x terms on one side.

2. Gather numbers

6x - 8 = 2x + 20Balance both sides. left side right side = 6x - 82x + 204x = 28x = _
Move numbers to the other side.

Move numbers to the other side.

3. Divide coefficient

6x - 8 = 2x + 20Balance both sides. left side right side = 4x2828 / 4 = 7x = _
Divide by the x coefficient.

Divide by the x coefficient.

4. Check

6x - 8 = 2x + 20Balance both sides. left side right side = x7x = 7x = 7
Substitute the answer back.
