sqrt(3x+7)=3x+5

Solution

3 x + 7 = 3 x + 5

Solution

x = - 1

Solution steps

3 x + 7 = 3 x + 5

Square both sides:

3 x + 7 = 9 x^{2} + 30 x + 25

3 x + 7 = 9 x^{2} + 30 x + 25

Solve

3 x + 7 = 9 x^{2} + 30 x + 25 : x = - 1, x = - 2

x = - 1, x = - 2

Verify Solutions:

x = - 1

True

, x = - 2

False

The solution is

x = - 1
