Answer:
x = - 1, y = 4
Step-by-step explanation:
A. We are going to use elimination method because we have +2y and -2y, and when we add these equations +2y and -2y are going to be eliminated.
B.
x + 2y = 7
<u>+ 3x - 2y = -11</u>
4x = - 4
x = - 1
-1 + 2y = 7
2y = 8
y = 4
46?
3(3) = 9
15-3=12
12(9)= 108
7(9)=63
ans : 183
