Question

What value of x is in the solution set of the inequality –5x – 15 > 10 + 20x?

–2
–1
0
1

Answer 1

0.333333333

Explanation:

-2x - 1 > 0 + 1x

Remove the 0 and collect like terms

-2× - 1> 1x

-3x> 1

Divide -3 and 1

-3X > 1

÷3 ÷3

Cancel the -3 and 3 sense they are the same and bring down the X

X> 1÷3

X> 0.333333333

Answer 2

collecting like terms

-5x-20x>10+15

-25x>25

divide both sides by -25

thus: x>25/-25

x>-1
