Answer:

The pair of shoes equal 18.

The boat equals 3

The chair equals 4

Step-by-step explanation:

Let x = shoes

You found the palm trees!

So the top picture would be

18 + x = 2x Subtract x from both sides

18 = x We found the value of the shoes.

Let's go so the last picture. We now know the shoes.

Let x = the boat now

18 = 6x Divide both sides by 6

x = 3 We found the value of the boat.

Finally, let's look at the second picture.

Let x = the chair now

3 + x = 7 Subtract 3 from both sides

x = 4 We found the value of the chair.
