ax + b = cx + d (mastery)

4 visual steps / collect x terms

1. Gather x

9x - 17 = -4x + 22Balance both sides. left side right side = 9x - 17-4x + 2213x = 39x = _
Put x terms on one side.

Put x terms on one side.

2. Gather numbers

9x - 17 = -4x + 22Balance both sides. left side right side = 9x - 17-4x + 2213x = 39x = _
Move numbers to the other side.

Move numbers to the other side.

3. Divide coefficient

9x - 17 = -4x + 22Balance both sides. left side right side = 13x3939 / 13 = 3x = _
Divide by the x coefficient.

Divide by the x coefficient.

4. Check

9x - 17 = -4x + 22Balance both sides. left side right side = x3x = 3x = 3
Substitute the answer back.
