Question

Solve the inequality -2x+20>4

Answer 1

`x<8`

Explanation:

`-2x+20>4`

Subtract 20 from both sides

`-2x+20-20>4-20`

Simplify

`-2x>-16`

Multiply both sides by -1 (reverse the inequality)

`(-2x)(-1)<(-16)(-1)`

Simplify

`2x<16`

Divide both sides by 2

`(2x)/(2) <(16)/(2)`

Simplify

`x<8`

Answer 2

x<8

Explanation:

-2x+20>4

-2x>-16

x<8
