solvefor y,x=(9y+4)/(y-7)

solve for

y, x = \frac{9 y + 4}{y - 7}

y = \frac{4 + 7 x}{x - 9}; x \neq = 9

Solution steps

x = \frac{9 y + 4}{y - 7}

Multiply both sides by

y - 7

x (y - 7) = 9 y + 4

Expand

x (y - 7) : y x - 7 x

y x - 7 x = 9 y + 4

Move

7 x

to the right side

y x = 9 y + 4 + 7 x

Move

9 y

to the left side

y x - 9 y = 4 + 7 x

Factor

y x - 9 y : y (x - 9)

y (x - 9) = 4 + 7 x

Divide both sides by

x - 9; x \neq = 9

y = \frac{4 + 7 x}{x - 9}; x \neq = 9

\frac{8}{3} = \frac{y - 9}{7 y + 4}

y^{- 2} + 2 y^{- 1} - 15 = 0

\frac{4 x + 1}{2 ( 8 x + 6 )} = 2 (4 x + 3)

0.00005 = \frac{8}{x ^{4}}

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