Solve the inequality then graph the solution set on real number line.
(2/5x)>7

2(x+7)-4>5(x-3)

1. Reiny

the easy one first:
2(x+7)-4>5(x-3)
2x + 14 - 4 > 5x - 15
-3x > -25
x < 25/3

for the 1st, I don't know why you put brackets around the left side, since it serves no purpose

did you mean 2/(5x) > 7
or
(2/5)x > 7

I will assume the last case:
mulitply both sides by 5
2x > 35
x > 35/2
