[latex]A+B=170,973[/latex] A is larger by [latex]47 km^{2} [/latex] The equation is [latex](B+473)+B=170,973[/latex] Subtract 473 from each side and add the B's [latex]B+473-473+B=170,973-473[/latex] [latex]2B=170,500[/latex] Now divide the number by the variable. [latex]170,500[/latex] ÷ [latex]2=85,250[/latex] [latex]B=85,250[/latex] To check, replace the B's with the value. [latex](85,250+473)+85,250=170,973[/latex] [latex]85,723+85,250=170,973[/latex] Answer: County A=[latex]85,723km^{2}[/latex] County B=[latex]85,250km^{2}[/latex]
