Step-by-step explanation:

The correct question is

Here are six number cards.

-4 -2 -1 5 6 8

Arrange the cards into three pairs with the same total.

step 1

Find the first pair

I take the numbers

-4 and 8

Adds the number to find out the total

-4+8=4

step 2

Find the second pair

I take the numbers

-2 and 6

Adds the number to find out the total

Remember that the total must be equal to the total of the first pair

-2+6=4 ---> is ok

step 3

Find the third pair

The remaining numbers are

-1 and 5

Check the sum

Remember that the total must be equal to 4

-1+5=4 ---> is ok

therefore

The three pairs are

-4 and 8

-2 and 6

-1 and 5
