The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$3 x = - 2 x - 20$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -20$$
Divide both parts of the equation by 5
We get the answer: x = -4
3*x+29 = 4*x-3*(2*x-3)
Expand brackets in the right part
3*x+29 = 4*x-3*2*x+3*3
Looking for similar summands in the right part:
29 + 3*x = 9 - 2*x
Move free summands (without x)
from left part to right part, we given:
$$3 x = - 2 x - 20$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -20$$
Divide both parts of the equation by 5
x = -20 / (5)
We get the answer: x = -4
