A + b = 45
a - b = 21
a = 21 + b
Use substitution
21 + b + b = 45
2b = 24
b = 12
45 - 12 = 33
The numbers are 33 and 12
Answer:
Divided into five equal parts
Answer:
b>44
Step-by-step explanation:
12/5<b-8/15
switch sides b-8/15>12/5
multiply both sides by 15 15(b-8)/15>12*15/5
simplify b-8>36
add 8 to both sides b-8+8>36+8
simplify
b>44
