Answer:

Explanation:

-4.2*(1 +2x) < -23.55 + 4.5

Use distributive property

-4.2*1 + 2x *(-4.2) < -23.55 + 4.5x

-4.2 - 8.4x < -23.55 + 4.5x

Add 8.4 x to both sides

-4.2 < -23.55 + 4.5x + 8.4x

-4.2 < -23.55 + 12.9x

Add 23.55 to both sides

-4.2 + 23.55 < 12.9x

19.35 < 12.9x

Divide both sides by 12.9

19.35/12.9 < x

1.5 < x
