Question

2x −6−5x≤9
What does it equal

Answer 1

x
`\geq`-5

Explanation:

Group like terms

2x-5x-6≤9

Add similar elements

-3x-6≤9

Add 6 to both sides:

-3x-6+6≤9+6

Simplify:

-3x≤15

Multiply both sides by -1: ( reverse the inequality)

(-3x)(-1)
`\geq`(15)(-1)

Simplify:

3x
`\geq`-15

Divide both sides by 3

3x/3
`\geq`-15/3

Simplify:

3x/3

Simplify:

-15/3

Answer:

x
`\geq`-5
