Question

A student's pay of $22 an hour is $4 more than twice the amount the student earns per hour at an internship. Enter and solve an equation to find the hourly pay of the internship.

__ = 2x + __


The internship pays $____
an hour.

Answer 1

$22 = 2x + $4

The internship pays $ 9 an hour.

Explanation:

$22 = 2x + $4

x represents the amount the student earns per hour at an internship

$22 - $4 = 2x + $4 - $4

$18 = 2x

divided both sides by 2 to get x alone

$18 / 2 = 2x / 2

$18 / 2 = x

$9 = x
