sqrt(7x+56)=3x+10

7 x + 56 = 3 x + 10

x = - 1

Solution steps

7 x + 56 = 3 x + 10

Square both sides:

7 x + 56 = 9 x^{2} + 60 x + 100

7 x + 56 = 9 x^{2} + 60 x + 100

Solve

7 x + 56 = 9 x^{2} + 60 x + 100 : x = - 1, x = - \frac{44}{9}

x = - 1, x = - \frac{44}{9}

Verify Solutions:

x = - 1

True

, x = - \frac{44}{9}

False

The solution is

x = - 1

7 + 6 x = x

x - 7 x x = 0

4 + 2 d - d + 6 = - 2

x^{- \frac{4}{3}} = \frac{1}{16}

\frac{1}{x} = 4
