x(x+5)-8=x^2+8

x (x + 5) - 8 = x^{2} + 8

x = \frac{16}{5}

Decimal Notation

x = 3.2

Solution steps

x (x + 5) - 8 = x^{2} + 8

Expand

x (x + 5) : x^{2} + 5 x

x^{2} + 5 x - 8 = x^{2} + 8

Move

8

to the right side

x^{2} + 5 x = x^{2} + 16

Move

x^{2}

to the left side

5 x = 16

Divide both sides by

5

x = \frac{16}{5}

t, at + b (t - b) = c

\frac{1}{10} - 2 \cdot (\frac{4 - x}{5}) - 7 \cdot (\frac{2 x + 7}{15}) = 0

x - \frac{2}{5} x - \frac{5}{7} (x - \frac{2}{5} x) = 6000

5 w + 3 = 2 w + 21

2 (3 - x) - 6 = - 5 x
