4/12 = x/9

\frac{4}{12} = \frac{x}{9}

x = 3

Solution steps

\frac{4}{12} = \frac{x}{9}

Switch sides

\frac{x}{9} = \frac{4}{12}

Cancel the common factor:

4

\frac{x}{9} = \frac{1}{3}

Multiply both sides by

9

x = 3

2 lo g_{10} (7) - 2 r = 0

Z + (3 + 2 i) = 5 + 20 i

50 = \frac{x}{2}

x, 5 x + 4 y = 32

\frac{x}{7} + 2 = 5
