ax + b = cx + d (signed)

4 visual steps / collect x terms

1. Gather x

-3x + 5 = 2x - 20Balance both sides. left side right side = -3x + 52x - 20-5x = -25x = _
Put x terms on one side.

Put x terms on one side.

2. Gather numbers

-3x + 5 = 2x - 20Balance both sides. left side right side = -3x + 52x - 20-5x = -25x = _
Move numbers to the other side.

Move numbers to the other side.

3. Divide coefficient

-3x + 5 = 2x - 20Balance both sides. left side right side = -5x-25-25 / -5 = 5x = _
Divide by the x coefficient.

Divide by the x coefficient.

4. Check

-3x + 5 = 2x - 20Balance both sides. left side right side = x5x = 5x = 5
Substitute the answer back.

Substitute the answer back.
