The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$- \frac{3 x}{5} = -7$$
Divide both parts of the equation by -3/5
We get the answer: x = 35/3
-(3/5)*x+7 = 0
Expand brackets in the left part
-3/5x+7 = 0
Move free summands (without x)
from left part to right part, we given:
$$- \frac{3 x}{5} = -7$$
Divide both parts of the equation by -3/5
x = -7 / (-3/5)
We get the answer: x = 35/3
