5 7/72=x+4 2/9 {minus 4 2/9 from both side}
x=5 7/72 - 4 2/9 = 7/8
x=7/8 or 0.875

5 7/72 = x + 4 2/9
subtract 4 2/9 each side
x = 5 7/72 - 4 2/9
Think in two parts: 5 - 4 and 7/72 - 2/9
5 - 4 = 1 and then we have to get LCD
7/72 - (2/9)(8/8) = 7/72 - 18/72 = - 9 / 72 reduces to (- 1 / 8)
so we have 1 - 1/8 = 7 /8

Turn them into improper fractions:
x+38/9=367/72
x+304/72=367/72
Subtract 304/72 from both sides:
x=367/72-304/72
x=63/72=7/8
Check:
5 7/72=7/8+4 2/9
5 7/72=63/72+4 16/72
5 7/72=4 79/72
5 7/72=5 7/72
I hope this helps!

Looking for a common multiple for the fractions, 72 will do.
We have 367/72 = x + 304/72. Then ,
63/72=x, or 7/8

To get the same denominator together, use 72 as the lcd
367/72=x+4 2/9 x 8/8=4 16/72
367/72=x+304/72
367/72-304/72=x+304/72-304/72
63/72=x
7/8=x----answer

What grade are you in? If you are in a grade where you are given such an equation and you are unable to solve then I am sorry but you are not making an effort.
Please try it on your own and you should be able to solve it.
Good Luck....
Trust me...you will thank me later....
