and by it i mean the equation

mathstudent55 · Answer

Let s = age of son
F = 3s + 1
s = 20
F = 3(20) + 1

idk

anonymous · Answer

idk

anonymous · Answer

s=20
f-1=3s
f=3*20+1=61

anonymous · Answer

1. F=3(20-1) 
2. F + 1 = 3(20) 
3. F - 1 = 3(20) 

these are the three i have to pick from

mathstudent55 · Answer

Look at the last one: F - 1 = 3(20)
add 1 to both sides: F = 3(20) + 1
That was my solution
