Do this for me

i am very lazy

First, let's turn all the numbers into improper fractions so that we can find the answer easier.

-2 = r -

- = r -

Now we have to isolate 'r'.

First, we have to make sure that the variable is on one side and all the numbers are on the other side.

To do this, we have to add to both sides.

In order to do this, we need to ensure that both fractions have a common denominator.

- = r -

Ensure that the denominators are the same:

= r -

+ = r

= r

Good luck!

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

$12. that is my answer.
