Answer:

2x - 5y =26.... equation i

x -5y =3..........equation ii

using subtition method

multiply equation (Ii) by -1

-1(x-5y =3

so you will have something like

-x +5y = -3...(III)

combine both equations

2x-5y =26

-x+5y = -3

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

2x-x +5y-5y= 26-3

You will have something like when you add them up

x=23

To find y when x=23 from equation (Ii)

x-5y =3

23-5y=3

collect the let terms

-5y=3-23

-5y=-20

y=20/5

y=4

x=23 and y =4
