Answer:
x=-2
y=3
Step-by-step explanation:
-3x+4y=18
multiply by 2
-6x+8y=36
and 6x+2y=-6
add
10 y=30
y=30/10=3
6x+2(3)=-6
6x=-6-6
6x=-12
x=-2
Its B trust i took the test and got it right
Let the number of corn acres be xx and the number of wheat acres be yy.
We are given that:
1- The total number of acres is 180, this means that:
xx + yy = 180 ..............> equation I
2- The number of corn acres is 3 times that of wheat. This means that:
xx = 3yy .........> equation II
Substitute with equation II in equation I to get the value of yy as follows:
xx + yy = 180
3yy + yy = 180
4yy = 180
yy = 45 acres
Now substitute with yy in equation II to get xx as follows:
xx = 3yy
xx = 3*45
xx = 135 acres
Based on the above calculations:
acres of corn = xx = 135 acres
acres of wheat = yy = 45 acres
