Question

find the value of x and y
1.mx-ny=m^2+n^2
x+y=2m
2.bx/a+ay/b=a^2+b^2
x+y=2ab

Answer 1

x+y=2m
x=2m-y put the value of x in mx-ny=m²+n²
2m²-my-ny=m²+n²
y(m+n)=m²-n²
y(m+n)=(m+n)(m-n)
y=m-n
now put the value of y in x+y=2m
x=m+n


value of x=m+n
value of y=m-n





b²x/a(1+y)=a²+b²
x+y=2ab
y=2ab-x pit the value of y in eq1
b²x/2a²b-ax+a=a²+b²
