Answer:
X= 2/5 y=-2
Explanation:
5x + 2y = -2
3x - 5y = 11.2
Using the elimination method
Multiply equation 1 by 3
Multiply equation 2 by 5
15x + 6y = -6
15x - 25y = 56
Subtrat 3 from 4
-31y= 62
Divide both sides by -31
y= -2
To arrive at x, substitute y= -2 in equation 1
5x + 2y = -2
5x + 2(-2)= -2
5x -4 = -2
Collect like terms
5x= -2+4
5x= 2
Divide both sides by 5
x= 2/5
