Question

solve the following pair of linear equations by substitution method x -y=3 and X/3+y/2=6​

Answer 1

Answer:

Step-by-step explanation:

x-y =3

x=y+3

Substituting the value of x in eq 2

(3+y)/3+y/2=6

(3+y)2+3y=12

6+2y+3y=12

5y=6

y=6/5

Answer 2

x-y=3....(1)

x/3+y/2=6

By l.c.m

2x+3y/6=6

2x+3y=36...(2)

from (1)

x=3+y...(3)

put x in eq (2)

2(3+y)+3y=36

6+2y+3y=36

6+5y=36

5y=36-6

5y=30

y=30/5

y=(6)

put value of y in eq (3)

x=3+6

x=9

hope its helps u ☺️❤️
