The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 60 - 7 x$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 60$$
Divide both parts of the equation by 4
We get the answer: x = 15
-15-3*x = -7*x+45
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 60 - 7 x$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 60$$
Divide both parts of the equation by 4
x = 60 / (4)
We get the answer: x = 15
