The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$3 x = 50 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$8 x = 50$$
Divide both parts of the equation by 8
We get the answer: x = 25/4
-3*(5-x) = 35-5*x
Expand brackets in the left part
-3*5+3*x = 35-5*x
Move free summands (without x)
from left part to right part, we given:
$$3 x = 50 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$8 x = 50$$
Divide both parts of the equation by 8
x = 50 / (8)
We get the answer: x = 25/4
