Question 541138
your problem

{{{ 3/7 - 18x = 3/9}}}

first you need to move the 3/7 with the 3/9 and will need a common denominator.

{{{(3/7) * (9/9) and (3/9) * (7/7)}}}


{{{27/63 - 18x = 21/63}}}

now we can move it:

{{{-18x = -6/63}}}

now devide each side by -18

{{{x = (-6/63)/-18}}}

so we multiply by the recripical

{{{x = (-6/63) * (-1/18)}}}

{{{ x = 6/1134}}}

simplify

{{{ x = 1/189}}}
