Question

Write the missing numbers in the table

The first row is done for you.

First number

5

7

-12

Second number

2

-3

Product of first and second numbers

10

24

Answer 1

-21 (on the second row) and -2 (on the third row)

Explanation:

Products are the multiples of the first and second numbers.

5 x 2 will give us 10 as seen in the first row.

For the second row, we know that 7 x -3 will give us -21

To do this, add -7 three times (-7 + -7 + -7)

For the third row, we need to do some algebra of guessing.

-12x = 24

x= -2

Where x is an unknown constant, though we found what x equals to.

I hope this helped, and I recommend watching some videos on algebra to help you :)
