Answer:
Step-by-step explanation:
First multiply both equations by 10
You the have 2x-5y=-4
5x-2y=-10
Using elimination method multiply equations 1 by 5 & equation 2 by 2 this is to eliminate x
10x -25y= -20
20x -4y= -20
Subtracting equation 2 from 1
We have -21y =0 so y =0
Substitute y=0 into any of the two equations and you have that
10x -4(0) =-20
10x-0= -20
10x=-20
X= -20/10
So therefore
X= -2
Remember you multiplied by 10 at the beginning so you have to divide now by 10
So x= -0.2 & y=0
