Question

2= -9+22-n I just want someone to answer this pls.

Answer 1

Answer:

n = 11

Step-by-step explanation:

Step 1: Write equation

2 = -9 + 22 - n

Step 2: Solve for n

1. Combine like terms:                    2 = 13 - n
2. Subtract 13 to both sides:           -11 = -n
3. Divide both sides by -1:               11 = n
4. Rewrite:                                        n = 11

Step 3: Check

Plug in n to verify it's a solution.

1. Substitute:          2 = -9 + 22 - 11
2. Add:                    2 = 13 - 11
3. Subtract:             2 = 2
