Answer:
x=30
Step-by-step explanation:
(30+x)+30+9x=360
We move all terms to the left:
(30+x)+30+9x-(360)=0
We add all the numbers together, and all the variables
(x+30)+9x+30-360=0
We add all the numbers together, and all the variables
9x+(x+30)-330=0
We get rid of parentheses
9x+x+30-330=0
We add all the numbers together, and all the variables
10x-300=0
We move all terms containing x to the left, all other terms to the right
10x=300
x=300/10
x=30
