x/5+7=1

OpenStudy (anonymous):

\[\Large \frac{x}{5}+7=1\]?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Ok well you first have to get x by itself but you have top move the 7 over to the other side, can you do that ?

OpenStudy (anonymous):

yes....x/5=-6?

OpenStudy (anonymous):

how do i get x by itself?

OpenStudy (anonymous):

x/5 = -6 is correct, now multiply both sides of the equation by 5

OpenStudy (anonymous):

ok well, you're diving by 5, so tog et rid of the 5 is you have to do the opposite of division: multiplication, so you multiply by 5

OpenStudy (anonymous):

\[\Large (\frac{x}{5}=-6) \times 5\]

OpenStudy (anonymous):

\[\Large x= -6 \times 5 \]

OpenStudy (anonymous):

so...x=-30?

OpenStudy (anonymous):

yep, now plug it back in the original formula and see if it works

OpenStudy (anonymous):

I did....whew! Thanks so much....you're a lifesaver:-)

OpenStudy (anonymous):

YW, anytime. =)
