Question

Which steps should be taken to solve the equation

2x + 3 = x + 5? Check all that apply.
Remove 3 x-tiles from both sides.
Remove 1 x-tile from both sides.
Remove 8 unit tiles from both sides.
Remove 5 unit tiles from both sides.
Remove 3 unit tiles from both sides.

Answer 1

Remove 3 unit tiles from both sides.

Remove 1 x-tile from both sides.

Explanation:

Removing 3 unit tiles from both sides, you get:

2x = x + 2

Removing 1 x-tile from both sides, you get:

x = 2

Answer 2

Remove 1 x-tile from both sides.

Remove 3 unit tiles from both sides.

Explanation:

2x + 3 = x + 5

First we want all the variables on one side

Subtract x from each side so Remove 1 x-tile from both sides.

x+3 = 5

Now we need to get all the constants on the same side

Subtract 3 from each side so Remove 3 unit tiles from both sides.

x = 5-3

x=2
