Question

Are 4x and 15 + x equivalent expressions? EXPLAIN

I need help FAST!

Answer 1

x=5

Explanation:

Step 1: you want to have x alone on one side so I will subtract one x from both sides (to remove the 1 x on the right side). Now we're left with 3x=15.

Step 2: Divide both sides by 3 (to remove the 3 in front of 3x). Now we have x=5.
