****hey user***

-5/14 * x = 7/12,

and we want to find x. So, get x by itself. Multiply both sides by -14/5. That leaves x alone on the left, and the following on the right:

=7/12 * -14/5 (reduce down before multiplying)

=7/6 * - 7/5 (multiply straight across, numerator by numerator, denominator by denominator)

= - 49/30

= -5/14 should be multiplied by -49/30 to make 7/12

(Check)

-5/14 * -49/30 =? 7/12 (reduce down on left where you can)

-1/14 * -49/6 (reduce still)

-1/2 * -7/6 (negative by a negative, so take them out)

1/2 * 7/6 = 7/12 (answer checks)
