4x+3y=26..........(1)
y=3x..............(2)

Substitute the value of y from (2) to (1)

4x+3(3x)=26
4x+9x=26
13x=26
Divide both sides of above equation by 13

13x/13=26/13
x=2

Now substitute the value of x  in (2)
y=3x
y=3(2)
y=6


(x,y)=(2,6)




Check
======
Put the value of x and y in (1)
4x+3y=26..........(1)
4(2)+3(6)=26
8+18=26
26=26
