Lucy has 12.5 pounds, Lisa has 7 1/14 pounds
To do these problems, you plug in the ‘n’ value given into the equation.
a. 6j - 3 : j = 4
6(4) - 3
24 - 3
21
b. 1/2b + 5 : b = 14
1/2(14) + 5
7 + 5
12
c. 8 + 4k : k = 3.5
8 + 4(3.5)
8 + 14
22
Step Number 1. is to Simplify

Step Number 2. <span>Simplify so you get </span>

Done! :)
