Solve the simultaneous equations 8 x + 5 y = 28 4 x + 5 y = 16 Will give Brainliest to right answer
No working out required

x=3, y=0.8

Step-by-step explanation:

8x+5y=28

4x+5y=16

Subtract the second simultaneous equation from the first.

You are left with: 4x=12

12/4=3

x=3

Substitute this back into one of the equations.

8(3)+5y=28

8*3=24

28-24=4

4=5y

4/5=0.8

y=0.8

x=3, y=4/5 or 0.8

Step-by-step explanation:

To find x and y, you can use elimination.

8x+5y=28

4x+5y=16

In both equations, there is a 5y. This way, we can cancel them out by subtracting the 2 equations.

4x=12

x=3

Now that we know x, we can plug it back into either equation to find y.

8(3)+5y=28

24+5y=28

5y=4

y=4/5=0.8

this is not the answer this is just a question. is this middle school math?
