A very small car that that weighs $9{,}000 \text{ Newtons}$ is parked on a $20 \text{-meter}​$ long bridge. The bridge weighs $15{,}000 \text{ N}$. The car is located $8.0\text{ meters}$ from the left side of the bridge. The bridge supports are located $0.5\text{ meters}$ from each edge of the bridge.
