Answer:
5
Step-by-step explanation:
4a + 6b = 24
6a - 12b = -6
Rewrite the first equation below. Divide both sides of the second equation by 2 and write below the first equation. Then add the equations.
4a + 6b = 24
+ 3a - 6b = -3
----------------------------
7a = 21
Divide both sides by 7.
a = 3
Now substitute 3 for a in the first equation and solve for b.
4a + 6b = 24
4(3) + 6b = 24
12 + 6b = 24
6b = 12
b = 2
a = 3, and b = 2
a + b = 3 + 2 = 5
