1. Consider the system of equations below. What could be the first step in solving by elimination?

3x + 5y = 16
3x + 2y = 10

O Add the two equations together.
O Add 5 to both sides of the first equation.
Ο Multiply the first equation by -1.
Ο Multiply the second equation by 2.​

Respuesta :

Answer:

Multiple the first equation by -1

Step-by-step explanation:

After doing this you add the two equations together and follow the systems of equations as normal

[tex]-3x+-5y=-16\\3x+2y=10\\-3y=-6\\\frac{-3y}{-3} =\frac{-6}{-3} \\y=2[/tex]

Therefore y = 2
