Answer:
B) (-1,-2)
Step-by-step explanation:
x-2y=3
3x+y=-5
The first step would be to rearrange an equation in order to be able to use the Substitution method. Personally, I believe it is easiest to rearrange the first one:
x-2y=3
x=3+2y
Now that the equation has been rearranged, the Substitution method can be used:
3(3+2y)+y=-5
9+6y+y=-5
9+7y=-5
7y=-14
y=-2
Now that we have solved for y, we already kind of know the answer, since only one option has this y value, but it doesn't hurt to double check by plugging in "y" into an equation:
x=3+2(-2)
x=3-4
x=-1
The solution for the system of equation would be (-1,-2)
