Answer:

Sorry - mod deleted a good ans provided by previous helper

ans is the third option down

Step-by-step explanation:

mistake is at

5x-10=10

instead of 5x=10, the next step should be ADDING 10 to both left n right

5x-10+10=10+10

5x=20

solving

x=4

y=5-2x=5-8

=-3


Answer:

The answer is C

Step-by-step explanation:

In 5x - 10 = 10

Because this is subtraction, you do the inverse operation

Addition

So -10 + 10 = 0 While 10+10=20

Because this one part is wrong, the rest of the problem is wrong

Hope this helps
