3/7x = 15 ==> x = 7x15/3 = 35

2007-03-11 07:15:20 · answer #3 · answered by physicist 4 · 1 0

Variant 1:
you meant (3/7)x=15
then x= 15/ (3/7) = 15 * (7/3) = 35

Variant 2"
you meant 3/(7x)=15
then 7x=3/15=1/5, x=1/35

Good luck.

x = 15/(3/7)
x = 35

3/7x = 15
3x = 15 * 7 = 105
x = 105/3
x = 35

Multiply by the reciprocal of the fraction to get rid of it on the left side of the equation. The reciprocal is just the "upside-down" version of the fraction.

x = 15 *7/3 = 35

2007-03-11 07:15:52 · answer #7 · answered by ecolink 7 · 0 0

multiply 7/3 for both sides

x = 15(7/3)

x = 35

you could look at it in pieces...

first multiply the 7 from both sides...
3x = 105
then divide by 3
x = 35


or you could just take the recipricle of whats by the x
so you'll multiply by the recipricle
(7/3) times (3/7)x = 15 times (7/3)
x = 35

3/7x = 15

7(3/7x) = 7(15)

3x = 105

3x/3 = 105 / 3

x = 105 / 3

x = 35
