Question

please help i will give metal

Answer 1

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?

Show that the solution to the system of equations 3x + y = 5 and 8x –7y = 6 is the same as the solution to the given system of equations

Show that the solution to the system of equations 8x – 5y = 11 and 7x – 8y = 6 is the same as the solution to the given system of equations

Show that the solution to the system of equations 15x + 13y = 17 and 7x – 8y = 6 is the same as the solution to the given system of equations

Show that the solution to the system of equations –13x + 15y = 17 and 7x – 8y = 6 is the same as the solution to the given system of equations

Answer 8

Show that the solution to the system of equations 3x + y = 5 and 8x -7y = 6 is the same as the solution to the given system of equations

Show that the solution to the system of equations 8x - 5y = 11 and 7x - 8y = 6 is the same as the solution to the given system of equations

Show that the solution to the system of equations 15x + 13y = 17 and 7x - 8y = 6 is the same as the solution to the given system of equations

Show that the solution to the system of equations -13x + 15y = 17 and 7x - 8y = 6 is the same as the solution to the given system of equations from a reply
