I'll do the first one.
3x + 15 = 0
3x = -15
x = -5
I'll be glad to check your work for the second problem.
Help!
Solve:
1. 3x + 15 = 0
2. 6x + 18 =0
thanks!

2. 6x + 18 =0
6x/6 = 18/6
x = 3??
6x/6 = 18/6
x = 3??
x = -3
You're on the right track, Good job!

Almost right.
But you forgot to subtract 18 from the right side of the equation.
6x + 18 =0
6x/6 = -18/6
x = -3
To check it, substitute -3 for x.
6(-3) + 18 = 0
-18 + 18 = 0
That's it!
