Question

Solve the inequality.

7x − 9 > 2x + 6
A) x > 3
B) x > 3/5
C) x > −3
D) x > −3/5

Answer 1

Option D.
`x> -3/5`

Explanation:

we have

`7x-9 > 2x + 6`

solve for x

Subtract 2x both sides

`7x-9-2x > 2x+6-2x`

`5x-9 > 6`

Adds 9 both sides

`5x-9-9 > 6-9`

`5x> -3`

Divide by 5 both sides

`5x/5> -3/5`

`x> -3/5`
