6x + 24 - 2x + 14 = 10 6(-7) + 24 – 2(-7) + 14 = 10
4x + 38 = 10 -42 + 24 + -2(-7) + 14 = 10
-42 + 24 + 14 + 14 = 10
-38 -38
-18 + 14 + 14 = 10

Mrs. Pasillas took her boys Gavin & Austin to the
pumpkin patch. Small Pumpkins were $3 each.
Large pumpkins were $ 7 each. She bought the

3x + 4 = 5x - 10 Steps
-3x
-3x
1) Get all of the x’s on 1 side.
4 = 2x - 10 2) Subtract 3x from both
sides.
+10
+10
3) Add 10 to both sides.
14 = 2x
2 2
4) Divide both sides by 2
7=x
