a+7=30a
Variable a cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by a.
a+7-30a=0
Subtract 30a from both sides.
-29a+7=0
Combine a and -30a to get -29a.
-29a=-7
Subtract 7 from both sides. Anything subtracted from zero gives its negation.
a=\frac{-7}{-29}
Divide both sides by -29.
a=\frac{7}{29}
Fraction \frac{-7}{-29} can be simplified to \frac{7}{29} by removing the negative sign from both the numerator and the denominator.
