Answer 1

1. 3.5

2. -2

Explanation:

1. 4x -5=9 (given)

4x = 14 ( addition property of equality) ( add 5 to both sides)

x = 3.5 ( division property of equality) ( divide both sides by 4)

2. 2x + 7 = 3 (given)

2x = -4 ( subtraction property of equality) ( subtract 7 for both sides)

x = -2 ( division property of equality) (divide both sides by 2)

1.) x = 3.5
