The solution
You have entered
[src]
17*p - 8 + -p - 7 + 15*p = 0
$$15 p + \left(\left(- p - 7\right) + \left(17 p - 8\right)\right) = 0$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without p)
from left part to right part, we given:
$$31 p = 15$$
Divide both parts of the equation by 31
We get the answer: p = 15/31
17*p-8-(p+7)+15*p = 0
Expand brackets in the left part
17*p-8-p-7+15*p = 0
Looking for similar summands in the left part:
-15 + 31*p = 0
Move free summands (without p)
from left part to right part, we given:
$$31 p = 15$$
Divide both parts of the equation by 31
p = 15 / (31)
We get the answer: p = 15/31
