What is x and y of 2x-4y=10&x+5y=40

Step-by-step explanation:

We are given that

When given these types of equations, we can manipulate them in order to cancel out a variable. Cancelling either the x or y works, choose which one is easier.

In this case, we can multiply the second equation by -2 and easily cancel out the x's

Now we can add the two equations

We can substitute y into the second equation and solve for x

Check:

2(15) - 4(5)

30 - 20 = 10

it works

3,000,540

step-by-step explanation:

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
