4/12 = x/3

\frac{4}{12} = \frac{x}{3}

x = 1

Solution steps

\frac{4}{12} = \frac{x}{3}

Switch sides

\frac{x}{3} = \frac{4}{12}

Cancel the common factor:

4

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

Multiply both sides by

3

x = 1

4 x - 2 - 7 = 7 x + 25 - 31

5 x + 7 = - 3 x + 31

h, c = (3 + y) h

x, 6 x + y = - 4

4 + x = 20
