Answer 1

Answer:

x=y=5

Step-by-step explanation:

5+5=10 5=5

may I correct

Answer 2

Answer:

x = 5

y = 5

Step-by-step explanation:

We will solve it as simultaneous equation.

Rearrange y = x to y - x = 0

---------

y - x = 0

y + x = 10

---------

Now we will subtract these together:

[ (y + x) - (y - x) ] = 10 - 0

( y + x - y + x) = 10

2x = 10

x = 5

So now to find y we will put x in the equation y = x

y = x

y = 5
