39*a 27*a 33 ---- + ---- = -- 5 5 10
$$\frac{27 a}{5} + \frac{39 a}{5} = \frac{33}{10}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Divide both parts of the equation by 66/5
We get the answer: a = 1/4
(39/5)*a+(27/5)*a = (33/10)
Expand brackets in the left part
39/5a+27/5a = (33/10)
Expand brackets in the right part
39/5a+27/5a = 33/10
Looking for similar summands in the left part:
66*a/5 = 33/10
Divide both parts of the equation by 66/5
a = 33/10 / (66/5)
We get the answer: a = 1/4
