Question

Solve this (they are all fractions)
6/11=n+7/9
​What does r equal

Answer 1

`\large\boxed{n=(-23)/(11)=-2(1)/(11)}`

Explanation:

`(6)/(11)=(n+7)/(9)\qquad\text{cross multiply}\\\\11(n+7)=(6)(9)\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\(11)(n)+(11)(7)=54\\\\11n+77=54\qquad\text{subtract 77 from both sides}\\\\11n=-23\qquad\text{divide both sides by 11}\\\\n=(-23)/(11)`

Answer 2

Explanation:

6/11= n+7/9

11.(n+7)=9.(6)

11n+77=54

11n=54-77

11n= -23

n= -23/11
