The solution
You have entered
[src]
32*x - 15 = 7*x - 10 - 14*x - 34*x
$$32 x - 15 = - 34 x + \left(- 14 x + \left(7 x - 10\right)\right)$$
Detail solution
Given the linear equation:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$32 x = 5 - 41 x$$
Move the summands with the unknown x
from the right part to the left part:
$$73 x = 5$$
Divide both parts of the equation by 73
We get the answer: x = 5/73
32*x-15 = 7*x-10-14*x-34*x
Looking for similar summands in the right part:
-15 + 32*x = -10 - 41*x
Move free summands (without x)
from left part to right part, we given:
$$32 x = 5 - 41 x$$
Move the summands with the unknown x
from the right part to the left part:
$$73 x = 5$$
Divide both parts of the equation by 73
x = 5 / (73)
We get the answer: x = 5/73
