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
