To find the width of Lance's banner, use division (area divided by length). Then use multiplication to times the width by 3 so you can find Evelyn's banner width. (I assume you know how to multiply and divide, but just comment if you'd like me to show you :) )
short explanation: 1) to add the 1st equation to the 2d; 2) to calculate the value of 'x', then to substitute x=13/5 into the 2d equation and calculate the value of 'y'.
