Answer:
- 120y + 720x = 600 (First option)
- y = 5 - 6x (2nd option)
- 2y + 12x = 10 (third option)
- x = 5/6 - y/6 (fifth option)
Explanation:
Correct answers only explained
------------------------------------------------------------------
We have the original equation as
72x + 12y = 60
If we multiply by 10 we get
720x + 120y = 600
First option
---------------------------------------------------------------
We can rewrite the original equation 72x + 12y = 60 as follows
Carry 72x to the right:
12y = 60 - 72x
Divide by 12
y = 5 - 6x
Second option
---------------------------------------------------------------
Rewrite 72x + 12y = 60 as
12y + 72x = 60 (same thing)
Divide by 6:
2y + 12x = 10
Third option
---------------------------------------------------------------
Rewrite 72x + 12y = 60 as
72x = 60 - 12y
Divide by 72
x = 60/72 -12y/72
Reduce to lowest fraction
x = 5/6 - y/6
Fifth option
------------------------------------------------
