Correct option is C- -x- 15-We need to find -x- such that -dfrac-x-6-3- is -7-160-We know that -dfrac-21-3- is -7-We thus get -7- if -x-6-21- -Longrightarrow- -x-15-

If $$\dfrac{x+6}{3} = 7$$, what is the value of $$x$$? ( using trail and error method)

Correct option is C. $$x= 15$$
We need to find $$x$$ such that $$\dfrac{x+6}{3}$$ is $$7$$.

We know that $$\dfrac{21}{3}$$ is $$7$$.

We thus get $$7$$ if $$x+6=21$$ $$\Longrightarrow$$ $$x=15$$
