Answer:
A. x = 3
Step-by-step explanation:
5x+15 + 2x = 24 +4x
7x+15=24+4x
7x+15-15=24+4x-15
7x=4x+9
7x-4x=4x+9-4x
3x=9
3x/3=9/3
x=3
Answer:
Answer A is correct
Step-by-step explanation:
5x + 15 + 2x = 24 + 4x
Take 4x to left side.
5x + 15 + 2x - 4x = 24
Take 15 to right side.
5x + 2x - 4x = 24 - 15
Combine like terms.
3x = 9
Divide both sides by 3.
x = 3
