Answer 1

Answer:

x=1

y=-1

Step-by-step explanation:

x = y+2

x+2y = 5

y+2 +2y = 5

3y +2 = 5

3y = 3

y=1

x=-1

Answer 2

Answer:

Step-by-step explanation:

Insert y+2 into your x so...

y+2+2y=5

Then solve...

Combine like terms so 2y+y is 2y^2 (squared)

and..

5-2 is 3

you are left with 2y^2 (squared) = 3 is 0.75
