1-23.

Solve each linear equation. Check your solutions. Homework Help ✎

  • Add 3 to both sides.

    −2x − 3 = 3
    +3 +3
    −2x = 6

  • Divide both sides by −2

  • x = −3

  • Add 3 to both sides.

    7 + 2x = 4x − 3
    +3 +3
    10 + 2x = 4x

  • Subtract 2x from both sides.

    10 + 2x = 4x
    -2x -2x
    10 = 2x

  • Divide both sides by 2.

  • x = 5

  • Refer to part (b).
