The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$4 x = 14 - 3 x$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = 14$$
Divide both parts of the equation by 7
We get the answer: x = 2
4*(x-2) = -(3*x-6)
Expand brackets in the left part
4*x-4*2 = -(3*x-6)
Expand brackets in the right part
4*x-4*2 = -3*x+6
Move free summands (without x)
from left part to right part, we given:
$$4 x = 14 - 3 x$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = 14$$
Divide both parts of the equation by 7
x = 14 / (7)
We get the answer: x = 2
