Question

Find the solution of the system of equations.
-4x + 5y = 13
X – 5y = –22

Answer 1

x=-7, y=3

Step-by-step explanation:

x-5y=-22

-4x+5y=13

Solve first equation for X

x=-22+5y

Sub in for X in the second equation

-4(-22+5y)+5y=13

88-20y+5y=13

88-15y=13

-15y=-75

15y=75

y=3

Sub in y

x=-22+5*3

x=-7

Answer 2

{y,x}={-7,-3}
