Question

Determine the value of x and y in the following systems of equations5x-2y=4 ; -2x+y=2.

Answer 1

Answer:(x,y)=(8,18)

Explanation:

Given

5x-2y=4-------1

Second Equation

-2x+y=2-----2

Now multiply equation 2 by 2 and it to equation 1

5x-4x+0=8

x=8

substitute it in equation 1

`5* 8-2* y=4`

36=2y

y=18

Therefore

(x,y)=(8,18)
