Answer:
1. 3.5
2. -2
Step-by-step 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)
