A number minus four times a second number is at least –4. Three times the first number, then added to the second number, is more than –3. If x represents the first number and y represents the second number, which system of inequalities best represents the problem situation? 2x−4y≥−4 3x+2y>−3 2 x minus 4 y is greater than or equal to negative 4, , 3 x plus 2 y is greater than negative 3, , , x−4y≥−4 3x+y>−3 x minus 4 y is greater than or equal to negative 4, , 3 x plus y is greater than negative 3, , , 2x−4y<−4 3x+y>−3 2x−4y<−4, , 3 x plus y is greater than negative 3, , , x−4y≤−4 3x+y>−3
