Answer:
y = 2
Step-by-step explanation:
(1) x + 2y = 9
(2) x - y = 3
Subtract (2) from (1)
3y = 6
y = 2
The y-coordinate is y = 2.
The graphs of the two equations intersect at (5, 2).
-10x +8y
--------------------
-5x - 4y ) 50x^2 - 32y^2
50x^2 + 40xy
-----------------
-40xy - 32y^2
-40xy -32y^2
-------------------
answer is -10x + 8y
You multily 9 by 5 since there is 5 wholes and those are divided into 9ths so 9by 5
