Question

II) solve the following pair of linear equation by
substitution method
7x-15y = 2 & x+2y=3​

Answer 1

x wala ek sath aur y wala ek sath

Answer 2

Answer:

x=1 y=1

Step-by-step explanation:

7x -15y=2

7x=2+15y

x=2+15y/7 sub this in eq 2

x+2y=3

2+15y/7 +2y=3

2+15y+14y/2=3

2+15y+14y=21

19y=19

y=1

then sub in eq 2

x+2y=3

x + 2=3

x=1
