4x+y=14 ---------------------------1
x+5y=13
x = 13 - 5y ------------------------2
Putting the value of x in 1
4 ( 13 - 5y ) + y = 14
52 - 20y + y = 14
-19y = 14 - 52
-19y = -38
y = -38/-19
y = 2 .
Putting the value of y in 2
x = 13 - 5y
x = 13 - 10
x = 3
x+5y=13
x = 13 - 5y ------------------------2

Putting the value of y in 2
x = 13 - 5y
x = 13 - 10
x = 3
how u did can nu tell mi pl

4x+y=14 ----1
x+5y=13
x = 13 - 5y --2
Substitute the value of x in equation 1
4 ( 13 - 5y ) + y = 14
52 - 20y + y = 14
-19y = 14 - 52
-19y = -38
y = -38/-19
y = 2 .
Substitute the value of y in equation 2
x = 13 - 5y
x = 13 - 10
x = 3
Therefore value of x=3,y =2
x+5y=13
x = 13 - 5y --2
Substitute the value of x in equation 1
4 ( 13 - 5y ) + y = 14
52 - 20y + y = 14
-19y = 14 - 52
-19y = -38
y = -38/-19
y = 2 .
Substitute the value of y in equation 2
x = 13 - 5y
x = 13 - 10
x = 3
Therefore value of x=3,y =2
