30x-7\times 1720x=21
Multiply both sides of the equation by 21, the least common multiple of 7,3.
30x-12040x=21
Multiply -7 and 1720 to get -12040.
-12010x=21
Combine 30x and -12040x to get -12010x.
x=\frac{21}{-12010}
Divide both sides by -12010.
x=-\frac{21}{12010}
Fraction \frac{21}{-12010} can be rewritten as -\frac{21}{12010} by extracting the negative sign.
