Now let’s start solving!

### Solutions and Answers!

First of all, let’s summarize the equations:

1 Donald Duck + 2 Mickey Mouse – 2 Jerry = 5 …………… **(Row 1)**

2 Mickey Mouse – 2 Jerry = 4 ……………. **(Row 2)**

1 Donald Duck + 4 Jerry = -7 …………… **(Row 3)**

1 Donald Duck + 1 Mickey Mouse + 1 Jerry = ?? ………. **(Row 4)**

The problem is to find the values of Donald Duck, Jerry and Mickey Mouse to be able to solve Row 4.

**In Row 1 equation, **we have *1 Donald Duck + 2 Mickey Mouse – 2 Jerry = 5*

Now, let’s consider the **Row 2 equation**: we have *2 Mickey Mouse – 2 Jerry = 4*

If we substitute the information from **Row 2** in the **Row 1** equation, we get

=> *1 Donald Duck + 2 Mickey Mouse – 2 Jerry = 5*

=> *1 Donald Duck + 4 = 5*

=> *1 Donald Duck = 5 – 4*

Hence, *1 Donald Duck = 1*

### That is not all!

Now we need to use the value of 1 Donald Duck to solve the **Row 3** equation, which is *1 Donald Duck + 4 Jerry = -7*

*=> 1 + 4 Jerry = -7*

*=> 4 Jerry = -7 -1*

*=> 4 Jerry = -8*

*=> 1 Jerry = -8 / 4*

*=> 1 Jerry = -2*

So, *1 Jerry = -2*

Now we need the value of 1 Jerry to solve the **Row 2** equation.

*2 Mickey Mouse – 2 Jerry = 4*

*=> 2 Mickey Mouse – (-2) = 4*

*=> 2 Mickey Mouse + 4 = 4*

*=> 1 Mickey Mouse = 4 – 4*

*=> 1 Mickey Mouse = 0*

We found, that *1 Mickey Mouse = 0*

Now, as we have the values of Donald Duck, Jerry and Mickey Mouse, we can solve the last row of the puzzle.

The **Row 4** equation is *1 Donald Duck + 1 Mickey Mouse + 1 Jerry = ??*

=> 1 + 0 + (-2) = ??

=> 1 + 0 – 2 = ??

=> -1

The final answer of this math question is *-1*.

**Well Done!**
