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:
$$- 4 x = 30$$
Divide both parts of the equation by -4
We get the answer: x = -15/2
x-5*(x+3) = 15
Expand brackets in the left part
x-5*x-5*3 = 15
Looking for similar summands in the left part:
-15 - 4*x = 15
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = 30$$
Divide both parts of the equation by -4
x = 30 / (-4)
We get the answer: x = -15/2
