Answer:
-15
15
3
Step-by-step explanation:
3(x-5)+2x=0
We add all the numbers together, and all the variables
2x+3(x-5)=0
We multiply parentheses
2x+3x-15=0
We add all the numbers together, and all the variables
5x-15=0
We move all terms containing x to the left, all other terms to the right
5x=15
x=15/5
x=3
