how would you do it?

you would get a common denominator between the two fractions:
(x/2) * (3/3) + (x/3) * (2/2) = 5
3x/6 + 2x/6 = 5
5x/6 = 5
x = 6

First: get rid of fractions > take the denominators and multiply them by everything:

2(3)(x/2) + 2(3)(x/3) = 2(3)(5)

Second: cross cancel "like terms" on both sides:

3x + 2x = 30


Third: combine "like" terms and divide both sides by 5:

5x = 30
5x/5 = 30/5
x = 6

1st thing to do is find a common denominator.
2*3 = 6.
2nd thing, since there are 2 fractions with x to be added together, we can multiply the entire equation by 6 to get
3x + 2x = 30
Now add the x's to get
5x=30
divide by 5 and
we get x = 6.

Like for any fraction work, you need to find the common denominator for the left side. It is 6 (i.e. 2 * 3)
x/2 = 3x/6 and x/3 = 2x/6. So,
3x/6 + 2x/6 = 5
5x/6 = 5
5x = 30
x = 6

multiply bothe sides by six to take away the denominators-
3x + 2x = 30
Combine like terms
5x = 30
divide both sides by 5 to get rid of the coefficient of x
x = 6
Check your work, although you would only do that on a test, because the answer is obviously x = 6

PS remember to script you variables, so you don't mix up "x" with a multiplication sign.

x/2 + x/3 = 5
multiply both sides by 6
3x + 2x = 30
5x = 30
x = 6

multiply both sides by 6 to clear the fractions. you get
3x + 2x = 30
5x = 30
x = 6
