sqrt(-x+400)= x/(60)+5

- x + 400 = \frac{x}{60} + 5

x = 300

Solution steps

- x + 400 = \frac{x}{60} + 5

Multiply both sides by

60

- x + 400 \cdot 60 = \frac{x}{60} \cdot 60 + 5 \cdot 60

Simplify

- x + 400 \cdot 60 = x + 300

Square both sides:

- 3600 x + 1440000 = x^{2} + 600 x + 90000

- 3600 x + 1440000 = x^{2} + 600 x + 90000

Solve

- 3600 x + 1440000 = x^{2} + 600 x + 90000 : x = 300, x = - 4500

x = 300, x = - 4500

Verify Solutions:

x = 300

True

, x = - 4500

False

The solution is

x = 300

4 x^{2} + 2 x + 9 = 9

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

x x + 7 = 12

w = 10 w - 16

3^{2} - 1^{2} + x^{2} = 1
