2*x + 9 = 13 - x
2x+9=13x2 x + 9 = 13 - x
Detail solution
Given the linear equation:
2*x+9 = 13-x

Move free summands (without x)
from left part to right part, we given:
2x=4x2 x = 4 - x
Move the summands with the unknown x
from the right part to the left part:
3x=43 x = 4
Divide both parts of the equation by 3
x = 4 / (3)

We get the answer: x = 4/3
