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:
$$\frac{15 x}{2} = 90$$
Divide both parts of the equation by 15/2
We get the answer: x = 12
(15*x-28)/2 = 76
Expand brackets in the left part
15*x/2-28/2 = 76
Move free summands (without x)
from left part to right part, we given:
$$\frac{15 x}{2} = 90$$
Divide both parts of the equation by 15/2
x = 90 / (15/2)
We get the answer: x = 12
