Question

find by substitution method: (2x/a+ y/b)=2
(x/a -y/b)=4
​

Answer 1

Step-by-step explanation:

let,x/a=m y/b=n

2m+n=2.......................1

m-n=2

m=2+n......................(substitute)

put value of m in equation 1

2(2+n)+n=2

4+2n+n=2

3n=-2

n=-2/3

put value of n in substitute

m=2+(-2/3)

m=(6-2)/3

m=3/3

m=1

x/a=m y/b=n

x/a=1 y/b=-2/3

x=a y=-2/3×b

3y=-2b
