If \dfrac{x1}{3}=k and k=3, what is the value of x?
7
8
9
10
Since k =3, we can substitute k for 3 in the equation,
\dfrac{x1}{3}=3
Multiply both sides by 3 to remove the denominator of the fraction
\dfrac{x1}{3}\cdotp 3 =3\cdotp 3
x1=9
Adding 1 to both sides gives the final result
x=10
Choice C is correct
