2(9x + 3) + 5x = 48 + 2x
18x + 6 + 5x = 48 + 2x
23x + 6 = 48 + 2x
23x - 2x = 48 - 6
21x = 42
x = 42/21
x = 2
Hi!
<h3>Let's use the guess and check method. </h3><h3>First, find numbers that when divided, equal 4, and are less than 20. </h3>
- 4/1 = 4
- 8/2 = 4
- 12/3 = 4
- 16/4 = 4
<h3>Now see if any of those pairs of numbers add up to 20. </h3>
- 4 + 1 = 5
- 8 + 2 = 10
- 12 + 3 = 15
- <u>16 + 4 = 20</u>
<h2>The answer is 16 and 4.</h2>
Hope this helps! :)
