TRUSTED Complete, trusted solutions and
explanations.

Question 1 (36)
1.1.

The following task example illustrate the Problem-Solving level according to CAPS:

1.1.1.

John had a few marbles. Today he played and doubled his number of marbles.
Then Thabo gave him three marbles for free. Jabu has 21 marbles now. How many
did he have before he started playing? Solve this problem using a suitable model.
(6)

Let’s use a bar model or an algebraic model to solve this.

Let the number of marbles John originally had be x.

 He doubled his marbles → Now he has 2x.
 Thabo gave him 3 more marbles → He now has 2x + 3.
 We know he ends up with 21 marbles.

Equation:

2x+3=21

Step-by-step solution:

1. Subtract 3 from both sides:

2x+3−3 = 21−3

=21−3
