Solve the following equation:
`ax-by=a+b`
`bx+ay=b-a`

ax+by=a+b bx+ay=b^2

Solve the following linear equations: ax + by = c bx + ay = 1+c

Solve the following simultaneous equations: ax+by=a-b;bx=ay+a+b

Solve the following system of equations bx + ay = 2ab and ax - by = a^(2) - b^(2) .

Solve the following system of equations: ax+by=c, x+ay=1+c

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

Solve the following system of equations in x and yax+by=1bx+ay=((a+b)^(2))/(a^(2)+b^(2))-1 or,bx+ay=(2ab)/(a^(2)+b^(2))

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

Solve the equation : sin ax+cos bx=0
