The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 2 x - 10$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = -10$$
Divide both parts of the equation by -5
We get the answer: x = 2
7-3*(x-1) = 2*x
Expand brackets in the left part
7-3*x+3*1 = 2*x
Looking for similar summands in the left part:
10 - 3*x = 2*x
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 2 x - 10$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = -10$$
Divide both parts of the equation by -5
x = -10 / (-5)
We get the answer: x = 2
