2) Based on the previous answer are the systems equivalent? In other words, do they have the same solution:

System a
6x-5y=1
-2x+2y=-1

System b
4x-3y=0
-2x+2y=-1

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
