(к-103):28=56

To solve the equation \((k - 103):28 = 56\), follow these steps: 1. Rewrite the equation as: \[ \frac{k - 103}{28} = 56 \] 2. Multiply both sides by 28 to eliminate the denominator: \[ k - 103 = 56 \times 28 \] 3. Calculate \(56 \times 28\): \[ 56 \times 28 = 1568 \] 4. Substitute this back into the equation: \[ k - 103 = 1568 \] 5. Add 103 to both sides to solve for \(k\): \[ k = 1568 + 103 \] 6. Perform the addition: \[ k = 1671 \] Thus, the solution is: \[ k = 1671 \]
