a+12=42a
Multiply both sides of the equation by 3.
a+12-42a=0
Subtract 42a from both sides.
-41a+12=0
Combine a and -42a to get -41a.
-41a=-12
Subtract 12 from both sides. Anything subtracted from zero gives its negation.
a=\frac{-12}{-41}
Divide both sides by -41.
a=\frac{12}{41}
Fraction \frac{-12}{-41} can be simplified to \frac{12}{41} by removing the negative sign from both the numerator and the denominator.
