0.75(8+e)=2-1.25e what does "e' equal

1 answer:

4 0

$0.75(8+e)=2-1.25e\qquad\text{use distributive property}\\\\(0.75)(8)+0.75e=2-1.25e\\\\6+0.75e=2-1.25e\qquad\text{subtract 6 from both sides}\\\\0.75e=-4-1.25e\qquad\text{add 1.25e to both sides}\\\\2e=-4\qquad\text{divide both sides by 2}\\\\\boxed{e=-2}$

Answer:

x = 5

x = 2

Step-by-step explanation:

2(2x + 4) = 8x - 12

2x + 4 = 4x - 6

x + 2 = 2x - 3

x = 5

Question 17

8/4 = (x + 2)/(2x - 2)

2(2x - 2) = x + 2

4x - 4 = x + 2

3x = 6

x = 2

x = 56*8/7
x = 8*8
x = 64 clipes
