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
