Question

3x+2/5 -2x+3/3 =3


i do not have a clue of how to start

Answer 1

Do you mean?


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

If so: Multiply by 15 to clear the denominators.

since 5 goes into 15 3 times you have

3(3x+2)

Since 3 goes into 15 5 times you have

5(2x+3)

and 3 times 15 = 45

9x+6 - (10x+15) = 45

9x + 6 - 10x -15 =45
-x -9 =45
-x = 54 so x = -54
This is the answer as long as I interpreted your problem correctly.
