[src]
3*x + 5 + x + 5 = 1 - x + 4
$$\left(x + 5\right) + \left(3 x + 5\right) = \left(1 - x\right) + 4$$
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:
$$4 x = - x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -5$$
Divide both parts of the equation by 5
We get the answer: x = -1
3*x+5+(x+5) = (1-x)+4
Expand brackets in the left part
3*x+5+x+5 = (1-x)+4
Expand brackets in the right part
3*x+5+x+5 = 1-x+4
Looking for similar summands in the left part:
10 + 4*x = 1-x+4
Looking for similar summands in the right part:
10 + 4*x = 5 - x
Move free summands (without x)
from left part to right part, we given:
$$4 x = - x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = -5$$
Divide both parts of the equation by 5
x = -5 / (5)
We get the answer: x = -1
