The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{7}{2} - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = \frac{7}{2}$$
Divide both parts of the equation by 2
We get the answer: x = 7/4
1/2 = 4-2*x
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{7}{2} - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = \frac{7}{2}$$
Divide both parts of the equation by 2
x = 7/2 / (2)
We get the answer: x = 7/4
