Linear functions SAT question

Math · Algebra · Easy · Answer it here, explanation included.

The function $g$ is defined by $g (x) = 6 x$ . For what value of $x$ is $g (x) = 54$ ?

Enter a number or fraction (like 3/17 or 0.176). Press Enter to check.

ExplanationShow

The correct answer is $9$ . It’s given that $g (x) = 6 x$ . Substituting $54$ for $g (x)$ in the given function yields $54 = 6 x$ . Dividing both sides of this equation by $6$ yields $x = 9$ . Therefore, the value of $x$ when $g (x) = 54$ is $9$ .
