10+5x=110
5x+10-10=110-10
5x=100
(5x)/5=100/5
x=20

x=20

Explanation:

First subtract 10 from both sides.
5x=100
Then, divide both sides by 5
x=20

The trick is to get x by itself by moving the other numbers around... That way you find that x=20.

Explanation:

In order to get our solution, we will work this in two steps:

  1. Move all terms, other than x and its coefficient, to the right-hand side
  2. Divide both sides by x's coefficient to get x alone

Step 1:
For this, we will subtract 10 from both sides. This will remove the 10 from the left hand side, and remove the same amount from the right hand side.

cancel(10)+5x-cancel(10)=110-10 rArr 5x=100

Step 2:
Now that we've moved everything else to the right hand side, we can divide both sides by x's coefficient. In this case, we will divide by 5:

(cancel(5)x)/cancel(5)=100/5 rArr x=100/5

Now we solve the division and get our answer:
x=100/5 rArr color(red)(x=20)

x = 20

Explanation:

Isolate the x term to one side so that we can solve for it:

Subtract 10 from both sides:
10+5x=110
color(blue)"-10 " " " " " color(blue)"-10"
------
5x = 100

Now divide by 5 to isolate x by itself:
(cancel5x)/cancel5 = 100/5
x = 20
