The correct Answer is:
To solve the equation \( (7x - 13) - (12x + 3) = 14 \), we will follow these steps: ### Step 1: Simplify the left side of the equation Start by distributing the negative sign across the second set of parentheses: \[ 7x - 13 - 12x - 3 = 14 \] ### Step 2: Combine like terms Combine the \( x \) terms and the constant terms: \[ (7x - 12x) + (-13 - 3) = 14 \] This simplifies to: \[ -5x - 16 = 14 \] ### Step 3: Isolate the variable term Next, add 16 to both sides of the equation to isolate the term with \( x \): \[ -5x - 16 + 16 = 14 + 16 \] This simplifies to: \[ -5x = 30 \] ### Step 4: Solve for \( x \) Now, divide both sides by -5 to solve for \( x \): \[ x = \frac{30}{-5} \] This simplifies to: \[ x = -6 \] ### Final Answer The value of \( x \) is \( -6 \). ---
