Question

solve the following linear equation a minus b x + a + b y is equals to 2 a square minus b square and a + b x minus y is equal to 4 a b

Answer 1

Answer:

(a-b)x-(a+b)x=a square -2ab-b2-a square- b square -2bx = -2bx(a+b)

x=(a+b)

:. (a+b)(a+b+y)=a square+b square

(a+b) square +(a+b)y +a square+ b square

y=-2ab by a+b answer
