Using elimination you can eliminate 'y' to find x first.
4x=24
+ 5x=12
-------------
9x=36
9/9 x=36/9
X=4
Next use substitution to plug 4 back in to 'x'
4(4)+y=24
16+y=24
-16 -16
------------
Y=8
X is 4 and Y is 8
The equation is y = -x - 1
Answer:
x=20 and y=100
Step-by-step explanation:
Using vertical angles, angle 1 and 3 equal each other. Therefore, x=80/4. Then, by using the sum of angle 1 and 3, 160, and using vertical angles again, we can find angle 2, which is (360-160)/2.
