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:
$$- 3 x = 21 - 10 x$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = 21$$
Divide both parts of the equation by 7
We get the answer: x = 3
-3*(x-1) = 24-10*x
Expand brackets in the left part
-3*x+3*1 = 24-10*x
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 21 - 10 x$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = 21$$
Divide both parts of the equation by 7
x = 21 / (7)
We get the answer: x = 3
