Elimination Method
Choose all that give a correct first step to solve the system of equations by the elimination method.
Equation A: 3x - 4y = 52
Equation B: 5x + y = 30
Multiply Equation B by -4
Equation A: -2x + 3y = -1
Equation B: x - 5y = 25
Multiply Equation B by 2
Equation A: 2x + y = 2
Equation B: -3x + 3y = 10
Multiply Equation A by 5
Equation A: 4x - y = 3
Equation B: 6x + 3y = 9
Multiply Equation A by-3
