<u>Assumption method: </u>

Assume all are postcards.

Total cost of postcards = 10 × $1

                                       = $10

Difference between total = $22 - $10

                                          = $12

Difference between subjects = $3 - $1

                                                 = $2

No. of magnets = $12 ÷ $2

                          = 6

8x+16=14x<br><br><br>checking my awnser
Firdavs [7]

8x + 16 = 14x

To solve this equation, move everything containing the variable you want to solve for on one side of the equation and everything else to the other side of the equation.

Let's start by subtracting 8x from both sides to have the variable x all on the right side of the equation. Once you subtract 8x from both sides, your equation will now look like this:

16 = 6x

To solve for the variable x, you want to divide both sides of the equation by 6 to isolate x and therefore find your answer. Divide both sides by 6 and your equation should look like this:

16/6 = x

Simplifying 16/6 into a mixed number ⇒ 2 2/3

Your answer is x = 16/6 or 2 2/3.
