Answer:

x=9, y=14

Step-by-step explanation:

2x+27+2x+27=90

4x+54=90

4x=36

x=9

4y-19 = y+23

3y= 42

y=14

x=19, y=14

4y-19 = y+23
combine like terms
4y-y=23+19
calculate
3y=42
divide both sides
y=14

2x+27
2x+27=45
subtract 27 from both sides
2x=45-27
calculate
2x=18
divide both sides
x=19

hope this helps :)
