Answer:
Step-by-step explanation:
So the equation is 1/x+1/y=1/7
Multiplying both sides by 7xy, we get
7y+7x=xy
So x+y=xy/7
Or x=-y+xy/7
So x can be:
1,2,3,4,5,6
Based on the given conditions, formulate:
If the fraction is defined, the denominator cannot equal 0.:
Append the inequality as the domain:
Reduce the fraction:
Multiply both sides of the equation by the common denominator:
Reduce the fractions:
Swap the sides:
Divide both sides of the equation by the coefficient of variable:
Cross out the common factor:
Find the intersection:
get the result:
