The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 11 - 8 x$$
Move the summands with the unknown x
from the right part to the left part:
$$x = 11$$
We get the answer: x = 11
12-7*x = -8*x+23
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 11 - 8 x$$
Move the summands with the unknown x
from the right part to the left part:
$$x = 11$$
We get the answer: x = 11
