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:
$$\frac{x}{2} = \frac{9}{4}$$
Divide both parts of the equation by 1/2
We get the answer: x = 9/2
x+3/4-x/2 = 3
Looking for similar summands in the left part:
3/4 + x/2 = 3
Move free summands (without x)
from left part to right part, we given:
$$\frac{x}{2} = \frac{9}{4}$$
Divide both parts of the equation by 1/2
x = 9/4 / (1/2)
We get the answer: x = 9/2
