Question 1106667: Which expression can be substituted for y in the top equation of the following system to solve the system by substitution? What is the solution?
3x−5y=13x-5y=1
3x−y=−7
My choices are as follows:
1) 7/3x, (−3/26, 173/26)
2)3x+7, (−3,−2)
3) 3/5x+1/5, (−3,−2)
4) −3x−7, (−17/9,4/3)
Thank you again and the "/" symbol is meaning "over" since i can not type it.

You can put this solution on YOUR website! The top equation has too many equal signs.
To sub for y, you 1st solve the equation for y.

/ is commonly used for fractions.
eg, 3/4, 7/8, etc.
