(bx)/(a)-(ay)/(b)+a+b=0 and bx-ay+2ab

Solve the following system of equations b(x)/(a)-a(y)/(b)+a+b=0,bx-ay+2ab=0

Solve: ax+by=a-b,quad bx-ay=a+b

The equation of a line perpendicular to line ax+by+c=0 and passing through (a,b) is equal to ................ A) bx-ay=0 B) bx+ay-2ab=0 C) bx+ay=0 D) bx-ay+ 2ab=0

(ax+by)^(2)-(ay+bx)^(2)

(bx ) /(a) + ( ay ) /( b) = a ^(2) + b ^(2) , x + y = 2ab

ax+by=a-b;bx-ay=a+b

Solve: ax - by = 1 bx + ay = 0

ax+by=1 bx+ay=2
