7 x - 5 = 3 x

x = \frac{5 ( 5 + 21 )}{8}

Decimal Notation

x = 5.98910 \dots

Solution steps

7 x - 5 = 3 x

Remove square roots

140 x = 16 x^{2} + 40 x + 25

Solve

140 x = 16 x^{2} + 40 x + 25 : x = \frac{5 ( 5 + 21 )}{8}, x = \frac{5 ( 5 - 21 )}{8}

x = \frac{5 ( 5 + 21 )}{8}, x = \frac{5 ( 5 - 21 )}{8}

Verify Solutions:

x = \frac{5 ( 5 + 21 )}{8}

True

, x = \frac{5 ( 5 - 21 )}{8}

False

The solution is

x = \frac{5 ( 5 + 21 )}{8}

x, f^{- 1} (x) = x

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

2 x - 5 = 7

x^{2} - 6 x + 9 = 2
