The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{5} = \frac{12}{5}$$
Divide both parts of the equation by 2/5
We get the answer: x = 6
((1/5)*x+7)/(1/2) = (82/5)
Expand brackets in the left part
1/5x+7)/1/2 = (82/5)
Expand brackets in the right part
1/5x+7)/1/2 = 82/5
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{5} = \frac{12}{5}$$
Divide both parts of the equation by 2/5
x = 12/5 / (2/5)
We get the answer: x = 6
