16-4a-3a=-20
Subtract 3a from both sides.
16-7a=-20
Combine -4a and -3a to get -7a.
-7a=-20-16
Subtract 16 from both sides.
-7a=-36
Subtract 16 from -20 to get -36.
a=\frac{-36}{-7}
Divide both sides by -7.
a=\frac{36}{7}
Fraction \frac{-36}{-7} can be simplified to \frac{36}{7} by removing the negative sign from both the numerator and the denominator.
