Answer: x=0, y= -2
Step-by-step explanation:
3x - 5y = 10 ........ equation i
6x + 3y = -6 .......... equation ii
Marybeth wants to solve the problem by multiplying the top equation by -2.
This will be
-2(3x - 5y =10)
-6x + 10y = -20 ...... equation iii
Combine equation iii and ii. This will be:
-6x + 10y = -20
6x + 3y = -6
Add both equations together
(-6x+6x)+(10y+3y) = (-20-6)
13y = -26
Divide both side by 13
13y/13 = -26/13
y = -2
Put the value of y into equation I
3x - 5y = 10
3x -5(-2) = 10
3x + 10= 10
3x = 10-10
3x= 0
x= 0
Therefore, X= 0, y = -2
