Answer:
-18
Step-by-step explanation:
Multiply the given equation by 2.
2(a +2b +6c) = 2(-9)
12c +2a +4b = -18
answer: 3, 4, 5, 6, 7
Now
3/2
3/4 * 2 = 6/4 = 3/2
the other side would be 15
because 15 is bigger than 12 and the 12 is the bottom line and then the other line going up is 15 so it's equal.
