Answer:
y=1,x=-2 so (-2,1)
x=1, y=-1 so (1,-1)
x=2.5, y=-2 so (2.5,-2)
Step-by-step explanation:
1.5y+x=−0.5, 2x+3y=−1 are the given equations.
If we were to multiple the first equation my 2 we would get
2(1.5y+x)=-0.5
3y+2x=-1
Meaning the two equations are the same so if you find a pair of numbers that works for one of theses equations it works for both.
Solutions:
y=1,x=-2 so (-2,1)
x=1, y=-1 so (1,-1)
Finally
x=2.5, y=-2 so (2.5,-2)
Hope this helps
