4-114.

Solve each equation below for the indicated variable, if possible. Show all steps. Homework Help ✎

  1. Solve for 

  • Solve by isolating the variable on one side of the equation by subtracting 22 from both sides.
    2x = 12 − 22
    2x = −10

  • x = −5

  1. Solve for 

  • Solve by isolating y on one side of the equation, and then simplify as much as possible.
    2x = y + 3
    Subtract 3 from both sides.

  • 2x − 3 = y

  1. Solve for 

  • Use the same strategy shown in parts (a) and (b) to solve parts (c) and (d).

  • y = 5 − 3x
