David gained 13 pounds over the winter He went on a diet and lost 27 pounds Then he reganed 3 pounds and weighed 1717 pounds How much did he wogh angrath

To find out how much David weighed before he gained 13 pounds over the winter, we can start by subtracting the weight he gained and the weight he lost from his current weight. Let's denote: - \( W \) as David's weight before he gained 13 pounds over the winter. Given: - David gained 13 pounds over the winter. - David lost 27 pounds. - David regained 3 pounds. - David's current weight is 1717 pounds. We can set up the equation as follows: \[ W + 13 - 27 + 3 = 1717 \] Solving this equation will give us David's weight before he gained 13 pounds over the winter. Solve the equation by following steps: - step0: Solve for \(W\): \(W+13-27+3=1717\) - step1: Calculate: \(W-11=1717\) - step2: Move the constant to the right side: \(W=1717+11\) - step3: Add the numbers: \(W=1728\) David weighed 1728 pounds before he gained 13 pounds over the winter.
