solvefor y,4x+7y+5xy=0

solve for

y, 4 x + 7 y + 5 x y = 0

y = - \frac{4 x}{7 + 5 x}; x \neq = - \frac{7}{5}

Solution steps

4 x + 7 y + 5 x y = 0

Move

4 x

to the right side

7 y + 5 x y = - 4 x

Factor

7 y + 5 x y : y (7 + 5 x)

y (7 + 5 x) = - 4 x

Divide both sides by

7 + 5 x; x \neq = - \frac{7}{5}

y = - \frac{4 x}{7 + 5 x}; x \neq = - \frac{7}{5}

\frac{x - 7}{90} - \frac{7}{10} = - 1

a, r = 8 (b - a)

\frac{2}{7} x + \frac{5}{7} x = 6

2 (x - 1) = x + 2

- 10 - 12 g = - 4 (3 g + 2.5)
