E.g. 6 + _ = 15. To find the answer, subtract 6 from 15 = 9. Answer: 6 + 9 = 15 This may be relevant or irrelevant to the question.
1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8
x -15 = 6+33 x-15 = 39 X = 54
Set up your equation: X+9=15. Then subtract 9 from 15. You get 15-9=6. Your answer is 6.
multiply by 2 then subtract 6
13/15 − 4/6 = 18/90 which reduces to 1/5
28/15 - 1/6 = 38/15 - 1/6 = 76/30 - 5/30 = 71/30 or 211/30
x+15+(-15)=6x+(15+(-15)=6x+(15-15)=6x+(0)=6x+0=6Add/subtract 0 from both sides,x=6
If you subtract 15 from -6 you get -21. If you worked out the problem on paper, this is what it would look like. -6 - 15 = ? (change the minus to a plus, and change the sign of 15 from positive to negative) -6 + -15 = ? ( now you can add negative 6 plus negative 15 which equals negative 21) -6 + -15 = -21

6m + 15 = 12 Subtract 15 from both sides: 6m = -3 Divide both sides by 6: m = -3/6 = -1/2
