Think About the Process:
You want to solve this system of equations using subtraction. The first step is to subtract the equations to eliminate y. What should be your next step? Then solve the system.
4 x - 5 y=11
8 x- 5 y=27

x=4, y=1

Step-by-step explanation:

Solve for X:

Multiply first equation by -1:

-4x+5y=-11

Subtract they Ys:

-4x+5y=-11

-8x-5y=27

4x=16

Divide by four:

x=4

Solve for Y:

Since we already have x, we only need to use one equation:

4(4)-5y=11

Simplify parenthesis by distribution:

16-5y=11

Subtract 16 from both sides:

-5y=-5

Divide both sides by -5:

y=1

Check:

4(4)-5(1)=11

16-5=11

11=11

8(4)-5(1)=27

32-5=27

27=27

i hope this helps u pls give brainliest and a thx ;)

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

if she was to only spend a dollar she can get 1lb
