Ok so what we have to do is 4+7+9=c
4+7=11
11+9=20
c=20
your answer is 20
Answer:
False?
Step-by-step explanation:
I'm pretty sure it's false because wouldn't it simplify to 5y? Sorry if I'm wrong. :)
The answer is 5. Work backwards: first add 7 to 9, then divide by 2, then subtract 3.
9+7=16
16/2=8
8-3=5
Cross Check:
5+3=8
8*2=16
16-7=9
Final Answer: 5
X + 9 = 2x - 3
<u>-x -x </u>
9 = x - 3
<u> +3 +3</u>
12 = x
A is the answer!! Hope it helps
