-2x - 5y = -1 8x + 4y = 16

To start solving the system of equations above, what number would be a good option to multiply the top equation by?

If someone could answer this asap that would really help also doing brainliest answer!

The good option to multiply the top equation by is -4

This is because, when we solve the equations, in the left side of first equation :-

☆ -2 can be multiplied by -4 to get the value 8 on the left side of second equation.

☆ This can help in easier elimination in the given set of equations.

■ The process is to be done as per the given below way :

Now the 8x on both equations can be cut.
