x 32/5 - x ---- = -------- 28/5 36/5
$$\frac{x}{\frac{28}{5}} = \frac{\frac{32}{5} - x}{\frac{36}{5}}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move the summands with the unknown x
from the right part to the left part:
$$\frac{20 x}{63} = \frac{8}{9}$$
Divide both parts of the equation by 20/63
We get the answer: x = 14/5
x/(28/5) = ((32/5)-x)/(36/5)
Expand brackets in the left part
x/28/5 = ((32/5)-x)/(36/5)
Expand brackets in the right part
x/28/5 = 32/5-x)/36/5
Move the summands with the unknown x
from the right part to the left part:
$$\frac{20 x}{63} = \frac{8}{9}$$
Divide both parts of the equation by 20/63
x = 8/9 / (20/63)
We get the answer: x = 14/5
