Question

Which of the following gives the value of x in the equation represented by the model given below?

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

The correct option is A 2

There are 4 tiles of 1 and 3 tiles of x on the LHS.

To eliminate the number, add 4 negative tiles on both sides.
Now, there is 1 x tile and four 1 tiles.

To eliminate x, add one negative tile of x on both sides.

Now, we get 2x = 4

Hence, x = 2
