lucyyy :
The second one, you cant just cancel terms out that are not equal. x is multiplied by y and 5 and you cant assume y=5

both are correct

MikeTheMikey :
when x is 0, y is anything, when y is 5, x is anything

neither. infinitely many solutions as a single equation with 2 variables cannot be solved

DP52 :
if x is 0 we cant divide it by 0 (x)?

Currito :
No one, if x=0 then y= R. If y=5 then x= R

Cameron :
The seccond cause x=0 works as a solution and the first eliminates the possibility of x=0 therefore is invalid

Mosa :
Neither. Answer: x=0, y = anything AND/OR y=5, x = anything

x can be any number I think

well if y=5 x can be any number do left is right

paulconnolly653 :
X can be anything because you put x(5-y)=0 where y=5 that means x(0)=0

2nd because the 1st assumes that x is not 0

X is any number not just 0

no idea can u explain pls

shay💤 :
both are correct, but the second one is the "more correct" approach because when you do cancel out X, you're eliminating 1 possibly solution

Nastja Tydgat :
both are right

both are correct just that in the first one you would have to substitute y with 5 to get x

tomrose487 :
First is better. It let's us put back in y to get 5x=5x which shows that x is any value not just 0.

Luca ✨🌸🔮 :
The first one is correct, as x could be any real number, not just 0.

Ashe☭ :
you can't divide by any term unless you can show 0 isn't a solution

Wiz :
The second method is correct but you ended it wrong. The solution is either x = 0 or y = 5 not necessarily both. If x = 0, y can be any number, if y = 5, x can be any number.

serena_1666 :
both are correct but you still gotta put y=5 in the formula for x but i usually use the right

Luka :
left is more correct. Y=5 but x can be anything

Infinitely many solutions 👍
