Question 827087: They were teaching us linear equations in class today but i did not understand how to solve them so i tried to use the example from our textbook which was
0.3-2=1.5x-0.4
-1.2x=1.6
x=1.6/-1.2
x=-4/3
but i don't understand how they received the answer. moving onto the homework we received they gave us a graph that had points a,b,c,d,and e plotted and gave us this information: the diagram shows the ferry routs between the points surrounding a harbor. the distance between the grid lines is 500ft so for example one question is route:A to D equation: y=0.2x+2,200 since they only gave us one side how would i solve this equation?
