Question

What is the answer to 4x - 6 ≥ 6x - 20

Answer 1

x
`\leq`7

Explanation:

4x-6
`\geq`6x-20

First get x on one side.

So substract 6x on each side to get:

4x-6x-6
`\geq`-20

Then add 6 on each side to get:

4x-6x
`\geq`-14

Simplify.

-2x
`\geq`-14

Divide each side by -2 to get x alone.

*Remember that when dividing by a negative sign is fliped.

x
`\leq`-14/-2

Simplify.

x
`\leq`7
