Question

Solve a 2 step linear equation algebraically. Show all work and all steps.

1.) 5x+3=23

2.) 42=18-4x

Answer 1

1.) x = 4 2.) x = - 6

Explanation:

1. 5x + 3 = 23

Isolate the variable. Subtract 3 from both sides.

5x = 20

Divide both sides by 5.

x = 4

____________

2. 42 = 18 - 4x

Isolate the variable. Subtract 18 from both sides.

24 = - 4x

Divide both sides by -4.

x = - 6
