Step-by-step explanation:
x+2y = 8
x= 8-2y........(1)
substitute in second equ
2x+3y = 13
2(8-2y)+3y =13
16 -4y+3y =13
16 -y= 13
-y = 13 -16
-y= -3
= y= 3
put in y value in 1 equation
x = 8-2y
x= 8 - 2(3)
x= 8-6
x=2

Hey mate !!!
Here is your answer
2x + 3y = 13 ......(i)
x + 2 y = 8 .......(ii)
from (i)
x + 2 y = 8
x = 8 - 2 y
Substituting the value of 'x' in (i)
2x + 3 y = 13
2 (8 - 2 y) + 3 y = 13
16 - 4 y + 3 y = 13
16 - y = 13
y = 16 - 13
y = 3
Substituting the value of 'y' in (ii)
x + 2 y = 8
x + 2 (3) = 8
x + 6 = 8
x = 8 - 6
x = 2
Answer :- x = 2 , y = 3
