PLEASE HELP ASAP!!!!!
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

Answer:

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 ;)

Answer:

4x -5y =11 eqn 1

8x-5y =27 eqn 2

then you subtract equation 1 from equation 2

4x=16

then you divide both side by 4

x = 4

put x=4 in eqn 1

4x-5y =11

4(4)-5y =11

16-5y =11

16-11=5y

5=5y

divide both side by 5

y = 1

:y=1,x=4
