2/5 x+2/3 = 4/5

\frac{2}{5} x + \frac{2}{3} = \frac{4}{5}

x = \frac{1}{3}

Decimal Notation

x = 0.33333 \dots

Solution steps

\frac{2}{5} x + \frac{2}{3} = \frac{4}{5}

Move

\frac{2}{3}

to the right side

\frac{2}{5} x = \frac{2}{15}

Multiply both sides by

5

2 x = \frac{2}{3}

Divide both sides by

2

x = \frac{1}{3}

x + 4 + 9 x + 18 = 12 (x + 2)

y = - 4 - 1

\frac{2 ( x - 3 )}{7} - \frac{1 - 6 x}{14} + \frac{5 ( x - 2 )}{2} = 1

3 b - 5 = 13

F, D = \frac{2}{3} (F + G)
