The solution
You have entered
[src]
25*x + 3*x + -10*x - 5 = -15
$$\left(- 10 x - 5\right) + \left(3 x + 25 x\right) = -15$$
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:
$$18 x = -10$$
Divide both parts of the equation by 18
We get the answer: x = -5/9
(25*x+3*x)-(10*x+5) = -15
Expand brackets in the left part
25*x+3*x-10*x-5 = -15
Looking for similar summands in the left part:
-5 + 18*x = -15
Move free summands (without x)
from left part to right part, we given:
$$18 x = -10$$
Divide both parts of the equation by 18
x = -10 / (18)
We get the answer: x = -5/9
