3/7 = 1/2-1/2 x

\frac{3}{7} = \frac{1}{2} - \frac{1}{2} x

x = \frac{1}{7}

Decimal Notation

x = 0.14285 \dots

Solution steps

\frac{3}{7} = \frac{1}{2} - \frac{1}{2} x

Switch sides

\frac{1}{2} - \frac{1}{2} x = \frac{3}{7}

Move

\frac{1}{2}

to the right side

- \frac{1}{2} x = - \frac{1}{14}

Multiply both sides by

- 2

x = \frac{1}{7}

9 x + 9 = 11 x - 2 x + 9

lo g_{8} (\frac{1}{2}) = - \frac{1}{3}

- 5 (7 + x) = 20

15 s - 100 = 350

x + \frac{1}{2} = 2
