9/5*(2/5 x-2)-3/10 x= 1/2

\frac{9}{5} \cdot (\frac{2}{5} x - 2) - \frac{3}{10} x = \frac{1}{2}

x = \frac{205}{21}

Decimal Notation

x = 9.76190 \dots

Solution steps

\frac{9}{5} (\frac{2}{5} x - 2) - \frac{3}{10} x = \frac{1}{2}

Multiply by LCM

18 (\frac{2}{5} x - 2) - 3 x = 5

Expand

18 (\frac{2}{5} x - 2) - 3 x : \frac{21}{5} x - 36

\frac{21}{5} x - 36 = 5

Multiply both sides by

5

21 x - 180 = 25

Move

180

to the right side

21 x = 205

Divide both sides by

21

x = \frac{205}{21}

\frac{y ^{6}}{y ^{3}}

∣ 2 x + 5 ∣ \leq 15

2 x^{2} - x - 3 x = 0

36 \cdot 3

\frac{2}{3} x = 1
