solvefor x,x+xy+y^2=7

solve for

x, x + x y + y^{2} = 7

x = \frac{7 - y ^{2}}{1 + y}; y \neq = - 1

Solution steps

x + x y + y^{2} = 7

Move

y^{2}

to the right side

x + x y = 7 - y^{2}

Factor

x + x y : x (1 + y)

x (1 + y) = 7 - y^{2}

Divide both sides by

1 + y; y \neq = - 1

x = \frac{7 - y ^{2}}{1 + y}; y \neq = - 1

\frac{- 5 - x}{- 3} = - 2

6 + 8 (4 q - 9) = 10 q

x, 4 x - y = - 9

y, 3 x - 4 y = 7

\frac{1}{4} x - 12 + \frac{2}{6} x = \frac{12}{3} - \frac{3}{6} - 5 - 7 x
