2y=sqrt(15-7y)

Solution

2 y = 15 - 7 y

Solution

y = \frac{5}{4}

+1

Decimal Notation

y = 1.25

Solution steps

2 y = 15 - 7 y

Square both sides:

4 y^{2} = 15 - 7 y

4 y^{2} = 15 - 7 y

Solve

4 y^{2} = 15 - 7 y : y = \frac{5}{4}, y = - 3

y = \frac{5}{4}, y = - 3

Verify Solutions:

y = \frac{5}{4}

True

, y = - 3

False

The solution is

y = \frac{5}{4}

5 = 3 + 4 x^{\frac{- 1}{6}}

(x^{2})^{\frac{3}{2}} = x

sqrt(7x-6)-9=3x-31

7 x - 6 - 9 = 3 x - 31
