I could help you on one problem but you would need to solve on the rest

For number 11

The solutions are:
x=18
y=5

49+3x=7x-23
Add like terms
49+3x=7x-23
49+23=7x-3x
72=4x
Divide both sides by 4
18=x
x=18

Find the value of y: 3x=11y-1
(corresponding angles)
Plug in the value of x:

3x=11y-1
3(18)=11y-1
55=11y


Add 1 to both sides
54+1=11y
55=11y

Divide both sides by 11
5=y
y=5
Thus:
x=18
y=5
