-5=sqrt(7x+2)-9

Solution

- 5 = 7 x + 2 - 9

Solution

x = 2

Solution steps

- 5 = 7 x + 2 - 9

Switch sides

7 x + 2 - 9 = - 5

Move

9

to the right side

7 x + 2 = 4

Square both sides:

7 x + 2 = 16

7 x + 2 = 16

Solve

7 x + 2 = 16 : x = 2

x = 2

Verify Solutions:

x = 2

True

The solution is

x = 2

Popular Examples

x + 10 = 2 - x

0= 2/(x^{1/3)}-2

0 = \frac{2}{x ^{\frac{1}{3}}} - 2

0=(-2t^2+16)/(sqrt(16-t^2))

0 = \frac{- 2 t ^{2} + 16}{16 - t ^{2}}

3 x - 1 + 9 = 8

4+sqrt(-3x+10)=x

4 + - 3 x + 10 = x
