Hello! To solve this we need to simplify it.
x+24=3x
Now we need to solve it backwards.
The variable x is postive, and the opposite of positive is negative. We subract -x from postive x to cancel it out and equal 0. Do this to both sides of the equation
x+24=3x
- x -x
0+24=2x
Now take 2x and do the opposite of that. Instead of multipling by 2, divide by 2.
24/2 = 12
2x/2 = x
Now we are left with x = 12. Let's plug it in.
(12) + 24 = 36
3 * (12) = 36
So x = 36
