-21.5+3.5n-3.5=24
Use the distributive property to multiply n-1 by 3.5.
-25+3.5n=24
Subtract 3.5 from -21.5 to get -25.
3.5n=24+25
Add 25 to both sides.
3.5n=49
Add 24 and 25 to get 49.
n=\frac{49}{3.5}
Divide both sides by 3.5.
n=\frac{490}{35}
Expand \frac{49}{3.5} by multiplying both numerator and the denominator by 10.
n=14
Divide 490 by 35 to get 14.
