(c+3)(n-1)

Answer 3

To check if the equation is solved correctly, let's simplify both sides step by step and see if they are equal:

Original equation: N(c+3) - (c+3) = N(c+3) - c - 3

Step 1: Apply the distributive property on the left-hand side (LHS) and right-hand side (RHS):

LHS: N * c + N * 3 - (c + 3) RHS: N * c + N * 3 - c - 3

Step 2: Combine like terms on both sides:

LHS: N * c - c + N * 3 - 3 RHS: N * c - c + N * 3 - 3

Step 3: Simplify further:

LHS: (N - 1) * c + (N * 3 - 3) RHS: (N - 1) * c + (N * 3 - 3)

As we can see, the left-hand side (LHS) and right-hand side (RHS) are identical. So, the equation is indeed solved correctly.

The solution shows that both sides of the equation are equal, and the equation holds true for any value of 'c' and 'N'.
