y=-5/11 and x=-23/11
Step-by-step explanation:
We can use the elimination method
We have
2x-7y = - 1 and
3x - 5y = - 4
We can multiply the first equation by 3 and the second by 2. This gives us
3 (2x-7y) = - 1 (3) and
2 (3x - 5y) = - 4 (2)
Distributing and simplifying results in
6x-21y=-3 and
6x-10y=-8
Subtracting the second equation from the first, we get
0x-11y=5
-11y=5
y=-5/11
putting this into the first equation, we get
2x-7 (-5/11) = -1
2x+35/11=-1
x = (-1-35/11) / 2
x=-23/11
