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.

We need to start by saying that y = 3
or 
Thus, the equation above is in the two variable form where y = 3
Thus, the required equation is
