Answer 2

Sure! Let's solve the equation step by step. The given equation is: (X - 12) - 15 = 43. Step 1: Start by simplifying the equation. First, let's simplify the left side of the equation: (X - 12) - 15 = X - 27. So now the equation becomes: X - 27 = 43. Step 2: Solve for X. To solve for X, we need to isolate it on one side of the equation. In this case, we want to get rid of the -27 on the left side. To do that, we'll add 27 to both sides of the equation: (X - 27) + 27 = 43 + 27. This simplifies to: X = 70. So the solution to the equation is X = 70. Now, let's check our solution by substituting X = 70 back into the original equation: (X - 12) - 15 = 43. (70 - 12) - 15 = 43. 58 - 15 = 43. 43 = 43. The left side of the equation matches the right side, so our solution is correct. Therefore, the value of X that satisfies the equation (X - 12) - 15 = 43 is X = 70.
