If: x/3 + 10 = 15 Then: x = 15
x=3 cross multiply and you get 15x=45 then divide 45 by 15 and you get 3
If the question is, What x 3 equals 15? Then 5 x 3 = 15 If the question is, What is 15 x 3? Then 15 x 3 = 45
x over 4= 2x+3 over 15
3 over 5 is the same as 9 over 15 so x = 7 over 15.
If: x/3 + 10 = 15 Then: x = 15
x=3 cross multiply and you get 15x=45 then divide 45 by 15 and you get 3
1 over 3 is a third. A third of 15 equals 5 (3 x 5 = 15)
If the question is, What x 3 equals 15? Then 5 x 3 = 15 If the question is, What is 15 x 3? Then 15 x 3 = 45
x over 4= 2x+3 over 15
3 over 5 is the same as 9 over 15 so x = 7 over 15.
-15 = x-3 x = -15+3 x = -12
The LCF is 45 because 15 x 3 equals 45 and 9 x 5 equals 45. Now, multiply 8 x 3 to get 24 and 2 x 5 equals 10. 24 plus 10 equals 34. The answer is 34 over 45.
Is it 15 over 40?

If: 1/3-1/5x = 15 then x work out as -3/220
x=3 becaus: 6x=x+15 5x=15 (-x) x=3 (divided by 5)
