Let the two nos be x and y

x-4-3y=0------1------

x+y+5=25------2------

taking eqn1

x=4+3y------3------

put this value of x in eqn 2 we get

4+3y+y+5=25

4y+9=25

4y=16

y=4

to find the value of x put y=4 in eqn 3

x=4+12

x=16

hence nos are 4 and 16

x-4-3y=0------1------

x+y+5=25------2------

taking eqn1

x=4+3y------3------

put this value of x in eqn 2 we get

4+3y+y+5=25

4y+9=25

4y=16

y=4

to find the value of x put y=4 in eqn 3

x=4+12

x=16

hence nos are 4 and 16
