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 c)
from left part to right part, we given:
$$2 c = -24$$
Divide both parts of the equation by 2
We get the answer: c = -12
(2-c)+3*(c+3) = -13
Expand brackets in the left part
2-c+3*c+3*3 = -13
Looking for similar summands in the left part:
11 + 2*c = -13
Move free summands (without c)
from left part to right part, we given:
$$2 c = -24$$
Divide both parts of the equation by 2
c = -24 / (2)
We get the answer: c = -12
