(25 points and brainliest) given the system of equations presented here:
4x + y = 4
2x + 7y = 28
which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated?
a. multiply the second equation by β1 to get β2x β 7y = β28
b. multiply the second equation by β4 to get β8x β 28y = β112
c. multiply the first equation by β7 to get β28x β 7y = β28
d. multiply the first equation by β2 to get β8x β 2y = β8
