The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$\frac{5 x}{2} = 95$$
Divide both parts of the equation by 5/2
We get the answer: x = 38
x/2+5+2*x = 100
Looking for similar summands in the left part:
5 + 5*x/2 = 100
Move free summands (without x)
from left part to right part, we given:
$$\frac{5 x}{2} = 95$$
Divide both parts of the equation by 5/2
x = 95 / (5/2)
We get the answer: x = 38
