Solution

x = \frac{5}{2}

+1

Decimal Notation

x = 2.5

Solution steps

40 - 6 x = 2 x

Square both sides:

40 - 6 x = 4 x^{2}

40 - 6 x = 4 x^{2}

Solve

40 - 6 x = 4 x^{2} : x = \frac{5}{2}, x = - 4

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

Verify Solutions:

x = \frac{5}{2}

True

, x = - 4

False

The solution is

x = \frac{5}{2}

Popular Examples

x - 2 - x = 0

(x-5)^{3/4}-27=0

(x - 5)^{\frac{3}{4}} - 27 = 0

sqrt(4x+1)+x=sqrt(5)

4 x + 1 + x = 5

0 = x^{2} - 9

x^{\frac{3}{4}} = - 8
