[src]
-5*(9*x - 5*x + 3) = -15
$$- 5 \left(\left(- 5 x + 9 x\right) + 3\right) = -15$$
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:
$$- 20 x = 0$$
Divide both parts of the equation by -20
We get the answer: x = 0
-5*(9*x-5*x+3) = -15
Expand brackets in the left part
-5*9*x+5*5*x-5*3 = -15
Looking for similar summands in the left part:
-15 - 20*x = -15
Move free summands (without x)
from left part to right part, we given:
$$- 20 x = 0$$
Divide both parts of the equation by -20
x = 0 / (-20)
We get the answer: x = 0
