actually no
OpenStudy (anonymous):
hold on so i got it wrong
OpenStudy (kuoministers):
5x = 5
we need to remove 5x to make it x
so we divide 5x to make x
so we need to divide the other side by 5 too
\[\frac{ 5x }{ 5 } = \frac{ 5 }{ 5 }\]
OpenStudy (kuoministers):
so answer would be x = 1
OpenStudy (kuoministers):
do you get it?
just read over what i typed. :)
