Question 2 • NC-Foundations of Math 1 (Fall) [1st 9 Weeks]

Which steps should be taken to solve the equation 2x + 3 = x + 5? Check all that apply.

Answer
A
Remove 3 x-tiles from both sides.
B
Remove 1 x-tile from both sides.
C
Remove 8 unit tiles from both sides.
D
Remove 5 unit tiles from both sides.
E
Remove 3 unit tiles from both sides.

Explanation

First remove 1 x-tile from both sides of 2x + 3 = x + 5. This leaves x + 3 = 5. Then remove 3 unit tiles from both sides, leaving x = 2. So the correct steps are removing 1 x-tile and removing 3 unit tiles from both sides.
