solvefor x,y= x/(x+z)

solve for

x, y = \frac{x}{x + z}

x = - \frac{yz}{y - 1}; y \neq = 1

Solution steps

y = \frac{x}{x + z}

Multiply both sides by

x + z

y (x + z) = x

Expand

y (x + z) : x y + yz

x y + yz = x

Move

yz

to the right side

x y = x - yz

Move

x

to the left side

x y - x = - yz

Factor

x y - x : x (y - 1)

x (y - 1) = - yz

Divide both sides by

y - 1; y \neq = 1

x = - \frac{yz}{y - 1}; y \neq = 1

\frac{96}{q} = - 12

\frac{x + 4}{x + 8} = 0.75

\frac{49 - x ^{2}}{x ^{2} + 7 x} = - 1

y, x = \frac{y - 3}{y + 3}

y, x = \frac{4}{y} - 2
