Answer:
Step-by-step 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
