The solution
You have entered
[src]
5 + x - 2 + 3*(x - 3) = 3*(4 - x) - 3
$$3 \left(x - 3\right) + \left(\left(x + 5\right) - 2\right) = 3 \left(4 - x\right) - 3$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$4 x = 15 - 3 x$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = 15$$
Divide both parts of the equation by 7
We get the answer: x = 15/7
5--x-2+3*(x-3) = 3*(4-x)-3
Expand brackets in the left part
5--x-2+3*x-3*3 = 3*(4-x)-3
Expand brackets in the right part
5--x-2+3*x-3*3 = 3*4-3*x-3
Looking for similar summands in the left part:
-6 + 4*x = 3*4-3*x-3
Looking for similar summands in the right part:
-6 + 4*x = 9 - 3*x
Move free summands (without x)
from left part to right part, we given:
$$4 x = 15 - 3 x$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = 15$$
Divide both parts of the equation by 7
x = 15 / (7)
We get the answer: x = 15/7
