Solve the following system of equations:
2x + 3y = 40
-2x + 2y = 20
We can add these equations to get a new equation. Then we can solve for y:
0 + 5y = 60
5y = 60
y = 12
2x + 3y = 40, plug in y = 12 and solve for x:
2x + 36 = 40
2x = 4
x = 2
Choice A
Answer:
3 Cars and 1 Van
Step-by-step explanation:
27-12=15
5x3=15
15-15=0
X would have a value of 27
Since 4 has y=4 which would be 16 you would add that with 65 get 81 then you would divide that by 3 and get your answer
