Step-by-step explanation:
5b + b = 42
6b = 42
/6 /6
b = 7
7(5) + 7 = 42
35 + 7 = 42
42=42

Could you show a better picture of the graph??
Each bottle of juice costs $3, so to find the total price of the bottles, you would have to multiply the number of bottles by $3, or:
3×J
Since she paid for them with a $20 bill, you need to subtract the total price of the bottles (shown above) from 20. Let's say "y" is the amount of change she receives:
y=20-(3×J)
Make an equation:
J = 1/2F - 10
Where 'J' represents Justin's age and 'F' represents his Father's age.
Plug in 12 for J:
12 = 1/2F - 10
Add 10 to both sides:
22 = 1/2F
Divide 1/2 to both sides or multiply by its reciprocal, 2:
F = 44
