(05.02) A system of equations is shown below:
x + 3y = 5 (equation 1)
7x - 8y = 6 (equation 2)
A student wants to prove that if equation 2 is kept unchanged and equation 1 is
replaced with the sum of equation 1 and a multiple of equation 2, the solution to the
new system of equations is the same as the solution to the original system of
equations. If equation 2 is multiplied by 1, which of the following steps should the
student use for the proof? (4 points)

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
