What is the question? I can't tell by the picture quality.
Are you asked to factor or what? I would write the 1st x-7y-12=0 and 3x+12y-36=0. and the 2nd one can be factored out. for example factor out a 3.
Answer:
it would take 20 miles and cost 10 dollars.
Step-by-step explanation: Like up the equations so that 50x=40x+200. When you solve for x (number of miles) you find that x=20. Use 20 in either equation (0.5x or 0.4x+2) to get 10 (total cost).
