3*(2 - 3*x) + 20 + 3*x = 2
$$3 x + \left(3 \left(2 - 3 x\right) + 20\right) = 2$$
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:
$$- 6 x = -24$$
Divide both parts of the equation by -6
We get the answer: x = 4
3*(2-3*x)+20+3*x = 2
Expand brackets in the left part
3*2-3*3*x+20+3*x = 2
Looking for similar summands in the left part:
26 - 6*x = 2
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = -24$$
Divide both parts of the equation by -6
x = -24 / (-6)
We get the answer: x = 4
