The first line mentions three coffees. Let's take the value of one coffee to be X

This means

X+X+X= 30

3X= 30

So, one coffee = 30/3 = 10

So, the value of one coffee is 10

The second line shows two cakes and a coffee.
Let's take the value of one cake to be Y:

This means

Y+Y+X= 20

Deriving the value of coffee from above, we get: So:

10+Y+Y = 20

Y+Y= 20 minus 10 = 10

So, one cake = 10 divided by 2 = 5

The third line has a cake, and two apples added together. Let's take the value of Apple to be Z

So, we get: Y+Z+Z=9

Taking the value of cake from the above we get

5+Z+Z= 9

Z+Z=9-5

2Z=4

Z=4/2

Z= 2

To solve the last equation we will use BODMAS and we get

5+2x10

20+5= 25

So the solution to the last equation is 25
