12 common denominator

2x/3 =3 divide 12 = 4 then 4multiply 2x =8x

Now 4 divide 12 = 3 then mulyiply 3 times x= 3x

Now 5 multiply 12 = 60

Then I have the following

8x - 3x=60

5x=60

DIVIDE

5 5

x=12

This is my thought process.

To verify your answer, plug it back into the original equation, like this:

. . . . .2x/3 - x/4 = 5

. . . . .2[12]/3 - [12]/4 ?=? 5

. . . . .24/3 - 12/4 ?=? 5

. . . . .8 - 3 ?=? 5

. . . . .5 = 5

Since the solution "checks", it is correct. Good work!
