Answer:

x = 21 degrees

y = 66 degrees

Step-by-step explanation:

Supplementary angles sum 180 degrees and complementary angles sum 90 degrees.

The first two upper angles are supplementary since they complete half a turn of a circle.

The relation is

(3x+5)+(6x-14)=180.

Joining like terms

9x-9=180

Dividing by 9

x - 1= 20 =>

x = 21 degrees

The first and the last angle are the same because they are formed by two parallel lines to a common side, so

3x-5=y-8 or

y=3x+3 = 63+3 =>

y = 66 degrees

How can I solve systems of equations by substitution method
almond37 [142]
This kind of hard to explain without an example, so I'll do my best...
All you have to do is isolate a variable on one side of the equals sign without a coefficient.  Ex:  x=2y+3  The x is all alone and ready to go into the second equation. 
Substitute into the second equation. Ex: 2x+5=3  Substitute: 2(2y+3)+5=3
I hope this helps!
