Answer:
y=5/2x
Step-by-step explanation:
5x=2y
y=5/2x
you cant get ordered pairs from this directly you will only get an equation
Common factor of 16 and 24 is 8
20 because if you take 20 half it that would be 10 then take away 4 that would then equal 6.
I would guess sometimes, but I'm not sure how something can be true and false at the same time. If something is both true and false it won't always be true and it won't never be true, so I'm guessing it's sometimes.
2 x - 5 y = 18 / * 4
3 x + 4 y = 4 / * 5 ( we will use the addition method )
--------------------------
8 x - 20 y = 72
+
15 x + 20 y = 20
-----------------------
23 x = 92
x = 92 : 23
x = 4
8 - 5 y = 18
- 5 y = 18 - 8
- 5 y = 10
y = 10 : ( - 5 )
y = - 2
Answer:
( x, y ) = ( 4, - 2 )
