Answer:
9/2
Step-by-step explanation:
6/7/x = 6x/7
so
6x/7 - 2/3 = 13/21
common denominator is 21
18x/21 - 14/21 = 13/21
18x/21 = 27/21
multiply both sides by 21
18x = 27
x = 27/18 or 9/2
Answer: hey! Your answer is x= 2/3
Step-by-step explanation:
1. To make our life easier we are going to simplify 6/7 divided by x to 6/7x
2. we see that in the original equation 2/3 is being subtracted so we have to do addition to cancel it out 13/21 + 2/3 simplified to equals 9/7
3. the equation is now 6/7x= 9/7 (remember that 7x we put in the beginning?) well there is a 7 on both sides one is being multipled and other is dividing so they both cancel each other
4. now the equation is 6=9x or 6/9 simplified to equals 2/3
and 2/3 is Your final answer
