Question

Solve each system by substitution

-5x+3y=22
8x-2y=-24​

Answer 1

`x= 193/22y= 1410/11`

Answer 2

Answer: x= -2

y=4

Explanation:

-5x+3y=22 I

8x-2y=-24 II

-------------------------

From second equation exp. y and return it in to first equation

y=(24+8x)/2

y=12+4x

-5x+3(12+4x)=22

-5x+36+12x=22

7x=-14

x= -2

y=12+4*(-2)

y=12-8

y=4
