-x --- + x + 7 = 3 3
$$\left(\frac{\left(-1\right) x}{3} + x\right) + 7 = 3$$
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:
$$\frac{2 x}{3} = -4$$
Divide both parts of the equation by 2/3
We get the answer: x = -6
-x/3+x+7 = 3
Looking for similar summands in the left part:
7 + 2*x/3 = 3
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{3} = -4$$
Divide both parts of the equation by 2/3
x = -4 / (2/3)
We get the answer: x = -6
