Which of these strategies would eliminate a variable in the system of equations?
(2z + 8y = -3
3x + 6y = -4
Choose all answers that apply:
Multiply the top equation by 3, multiply the bottom equation by -2, then add the
equations.
Multiply the top equation by -4, multiply the bottom equation by 3, then add the
equations.
Multiply the top equation by 3, multiply the bottom equation by 4, then subtract the
bottom equation from the top equation.
