Question

The value of x in the equation shown by the algebraic model is .

• A. 4
• B. 5
• C. 3

Answer 1

The correct option is A 4

There are three x tiles and two 1 tiles on the LHS.

To remove the constant 2 from the LHS, add 2 negative tiles on both the sides.

There are two x tiles and four 1 tiles on the right side of the equation.

To eliminate x on the right side, add two negative x tiles on both the sides.

Hence, x = 4
