The equations –a – 7b = 14 and –4a – 14b = 28 represent a system of linear equations. which statement correctly explains how to eliminate the variable b when solving the system of equations?
a. multiply the first equation by –2 and add it to the second equation. then solve the resulting equation, –2a = 0.
b. multiply the first equation by 2 and add it to the second equation. then solve the resulting equation, –2a = 0.
c. divide the second equation by –4 and add it to the first equation.
d. divide the second equation by 4 and add it to the first equation.
