Question

Ax +by =a*2 + b*2 , x/a + y/b =2 by substitution method

Answer 1

Answer: x=a   and y=b

Step-by-step explanation :ax+by=a^2+b^2------1 equation

x/a+y/b=2------2 equation

ax+by=a^2+b^2

x=a^2+b^2-by/a--------3equation

a^2+b^2-by/a^2+y/b=2

a^2b+b^3-b^2y+a^2y/a^2y=2

a^2b +b^3-b^2y+a^2y=2a^2y

2a^2y-a^2y+b^2y=a^2b+b^3

a^2y+b^2y=a^2b+b^3

y=a^2b+b^3/a^2+b^2

y=b

x=a^2+b^2-by/a

 x=a^2+b^2-b*b/a

 x=a^2+b^2-b^2/a

 x=a^2/a

 x=a
