4sqrt(x)= 2/5 x

4 x = \frac{2}{5} x

x = 0, x = 100

Solution steps

4 x = \frac{2}{5} x

Multiply both sides by

5

4 x \cdot 5 = \frac{2}{5} x \cdot 5

Simplify

20 x = 2 x

Square both sides:

400 x = 4 x^{2}

400 x = 4 x^{2}

Solve

400 x = 4 x^{2} : x = 0, x = 100

x = 0, x = 100

Verify Solutions:

x = 0

True

, x = 100

True

The solutions are

x = 0, x = 100

16 - x^{2} = 3 x

x^{2} + 6 x = 1

4 y = y + 3

y^{\frac{3}{2}} = 9 y

3 2 x - 3 - 20 = 7
