how to do -48= 2q and 13 n/10

divide

-48= 2q

-48/2 = q

-24 = q

I don't know what you mean by 13 n/10

To solve the equation -48 = 2q + 13n/10, we need to isolate the variable q. Here's how to do it step by step:

Step 1: Combine like terms
Start by rearranging the equation to have all the terms with q on one side of the equation and the constant terms on the other side.

-48 - 13n/10 = 2q

Step 2: Simplify the equation
To simplify the equation, determine the common denominator for the terms on the left side. In this case, the common denominator is 10. Multiply both sides of the equation by 10 to get rid of the fraction.

-480 - 13n = 20q

Step 3: Isolate the variable q
Finally, divide both sides of the equation by 20 to isolate the variable q.

q = (-480 - 13n) / 20

That's it! You have solved the equation and isolated the variable q.
