1: Move variable to one side
2: Add/subtract
3: multiply/divide
1) Solve. 3x + 2 = 4x - 1
You need to get the variables on one
side of the equation. It does not
matter which variable you move.
Try to move the one that will keep
your variable positive.
Solve the equation. Check your answer.
4b + 2 = 3b
8y - 9 = -3y + 2
Solve the equation. Check your answer.
0.5 + 0.3y = 0.7y – 0.3
1) 4a – 3 = 2a + 7
2) -3r + 9 = -4r + 5
3) 3d + 8 = 2d – 17
4) 2x – 7 = 5x – 10
