Answer:
x= 7 y= 9 (7,9)
Step-by-step explanation:
solve by using system if equations. multiply top answer by 2, giving u 2y=2x+4 and y=2x-5 subtract the equations. y=9 (the x cancels out) then put 9 in for y. 9=x+2. subtract 2. giving u 7. and now x =7
To find the percent of increase take the difference of the two divided by the original. (62-55)/55 = .12727272727. So 13% if they want you to round to the nearest percent.
