sqrt(y)-1=-5/9 y+7

y - 1 = - \frac{5}{9} y + 7

y = 9

Solution steps

y - 1 = - \frac{5}{9} y + 7

Multiply both sides by

9

y \cdot 9 - 1 \cdot 9 = - \frac{5}{9} y \cdot 9 + 7 \cdot 9

Simplify

9 y - 9 = - 5 y + 63

Remove square roots

81 y = 25 y^{2} - 720 y + 5184

Solve

81 y = 25 y^{2} - 720 y + 5184 : y = \frac{576}{25}, y = 9

y = \frac{576}{25}, y = 9

Verify Solutions:

y = \frac{576}{25}

False

, y = 9

True

The solution is

y = 9

\frac{x + 4}{6} + 3 = 4

x - 1 = - 1 + x

2 x + 3 x + 2 = 2

x = 19

x + 9 = 11
