Answer: a=5
Step-by-step explanation:
Rearrange terms:
3a+15=-5a+55
Subtract 15 from both sides of the equation:
3a+15-15=-5a+55-15
Subtract the numbers:
15-15 55-15
3a=-5+40
Add 5a to both sides of the equation:
3a+5a=-5a+40+5a
Simplify:
8a=40
Divide both sides of the equation by the same term:
8a/8=40/8
Simplify: a=5
Sorry for the wait :(
