Answer:
x = 5/2, y = -1
x*y = 5/2*-1 = -5/2
Step-by-step explanation:
First we solve the system
2x-5y = 10
x = 5 + 5y/2
4x + 3y = 7
4(5 + 5y/2) + 3y = 7
20 +10y + 3y = 7
-13 = 13y
y = -1
Now go back to the other equation
2x - 5y = 10
2x - 5(-1) = 10
2x + 5 = 10
2x = 5
x = 5/2
Now we multiply x and y together
Answer:
-28x
Step-by-step explanation:
I'd presume you forgot the x in your answer when you turned it in?
Answer:
x = -2
Step-by-step explanation:
12 + x = 10
x = 10 - 12
x = -2
