Answer:
X = 5
Step-by-step explanation:
To solve for x, you need to get x to one side and everything else to the other side.
3x+20=x+30
Since there is only one positive x on the right, we can subtract it from both sides. This moves it over.
2x+20=30
Since there is a +20 on the same side we put our x, we need to subtract it from both sides to move it over.
2x = 10
Now x is being multiplied by 2. To get rid of it, we divide both sides by 2.
x = 5
