Have not a clue please help to figure this one out: P-Q=-R, for Q

Do you wish to solve for Q?
If so, subtract P from both sides.
P-P-Q=-R-P
Combine terms.
-Q=-R-P
Multiply by -1
Q = R+P

a=s2

To solve for Q in the equation P-Q=-R, you can follow these steps:

1. Start with the given equation: P-Q=-R.

2. To isolate Q, you need to get rid of the -Q term on the left side. The goal is to get Q by itself on one side of the equation.

3. To eliminate -Q, you can add Q to both sides of the equation. This is done to maintain the balance of the equation.

(P-Q) + Q = -R + Q

4. Simplify the equation by combining like terms. On the left side, the -Q and +Q terms cancel out since they are additive inverses of each other.

P = -R + Q

5. To solve for Q, you want to isolate it on one side of the equation. Since the -R term is currently being added to Q, you can move it to the other side by subtracting -R from both sides.

P + R = -R + Q - R

6. Simplify the equation by combining like terms on the right side.

P + R = Q

7. Finally, rearrange the equation to have Q on the left side.

Q = P + R

Therefore, the solution for Q in the equation P-Q=-R is Q = P + R.
