6/9 = u/(12)

\frac{6}{9} = \frac{u}{12}

u = 8

Solution steps

\frac{6}{9} = \frac{u}{12}

Switch sides

\frac{u}{12} = \frac{6}{9}

Cancel the common factor:

3

\frac{u}{12} = \frac{2}{3}

Multiply both sides by

12

u = 8

2 x - 1 = 6 + x

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

\frac{1}{2} (x + \frac{1}{3}) + \frac{1}{4} (\frac{2}{3} x - \frac{1}{6}) = x

y = lo g_{10} (100)

y, 3 x - y = 12
