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

If $2 + x = 60$ , what is the value of $16 + 8 x$ ?

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

ExplanationShow

The correct answer is $480$ . Multiplying both sides of the given equation by $8$ yields $8 (2 + x) = 8 (60)$ , or $16 + 8 x = 480$ . Therefore, if $2 + x = 60$ , the value of $16 + 8 x$ is $480$ .
