Prove that the solution for the equivalent system is the same as the solution for the original system of equations.

Question

This is what i have so far:
2.	A system of equations is given below.
2x + 7y = 1
-3x – 4y = 5
a.	Create an equivalent system of equations by replacing the first equation by multiplying the first equation by an integer other than 1, and adding it to the second equation.  
2 x 3 + 7 x 3 = 3
6x + 21y = 3
+-3x -4y  +5
3x + 17y = 8
b.	Use any method to solve the equivalent system of equations (the new first equation with the original second equation).  I used the substitution method and substituted x and y for 3.
