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.
b. Use any method to solve the equivalent system of equations (the new first equation with the original second equation).
c. Prove that the solution for the equivalent system is the same as the solution for the original system of equations.

i did but the thing is i didn't know what parts to put for a . b . c. it was all mixed up etc.

sparklestaraa · Answer

can i ask a different ? to u

daniellelovee · Answer

oh for a what they want you to do is multiply by a number that is not 1 and add that value into the second equation
