3x-4y=7 3x+2y=-5 When the second equation is subtracted from the first, the resulting equation is __ 2y=12 -6y=12 -6y=-12 -2y=-12

To solve the system of equations, we can use the elimination method. By subtracting the second equation from the first equation, we can eliminate the variable x.<br /><br />Given equations:<br />$3x - 4y = 7$<br />$3x + 2y = -5$<br /><br />Subtracting the second equation from the first equation:<br />$(3x - 4y) - (3x + 2y) = 7 - (-5)$<br />$3x - 4y - 3x - 2y = 7 + 5$<br />$-6y = 12$<br /><br />Therefore, the resulting equation is $-6y = 12$.
