Answer:
I'd times the first equation by 3 and the second equation by 2. Giving:
6x + 15y = 21
6x + 8y = 12
then I'd subtract the second from the first
6x-6x + 15y-8y = 21-12
7y = 9
y = 7/9
then sub y into one of the equations and solve for x.
Hello!

3 - h = 8
Isolate for h by subtracting 3 by both sides:
3 - 3 - h = 8 - 3
- h = 5
Multiply both sides by -1 to make h positive:
-h(-1) = 5(-1)
h = -5
