3 visual steps / linear isolate x

1. Remove constant

3x + 4 = 19Balance both sides. left side right side = 3x + 4193x = 15x = _
Undo the visible number.

Undo the visible number.

2. Divide coefficient

3x + 4 = 19Balance both sides. left side right side = 3x1515 / 3 = 5x = _
Divide by the x coefficient.

Divide by the x coefficient.
