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:
$$5 x = 9 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = 9$$
Divide both parts of the equation by 7
We get the answer: x = 9/7
5*(x-3) = -2*(3+x)
Expand brackets in the left part
5*x-5*3 = -2*(3+x)
Expand brackets in the right part
5*x-5*3 = -2*3-2*x
Move free summands (without x)
from left part to right part, we given:
$$5 x = 9 - 2 x$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = 9$$
Divide both parts of the equation by 7
x = 9 / (7)
We get the answer: x = 9/7
