30=5(r/(5-3))

30 = 5 (\frac{r}{5 - 3})

r = 12

Solution steps

30 = 5 (\frac{r}{5 - 3})

Switch sides

5 (\frac{r}{5 - 3}) = 30

Divide both sides by

5

\frac{r}{2} = 6

Multiply both sides by

2

r = 12

6 x = 5 + 2 x

x, x - \frac{y}{2} = 2

x, 2 x + 3 y = 1470

3 x + 5 x = 24

7 = \frac{x}{12}
