Answer:
8 red haired and 42 brown haired
Step-by-step explanation:
I chose a random number to start off with (which is 8) and I multiplied it by 5. 
8•5=40 and then you have to add 2, so you get 42.
42+8 = 50
The equation would be (5x+2)+x where 'x' is the number of people with red hair.

Answer:
19 bars =<u> 76 more ores.</u>  22 bars = <u>88 total ores.</u>
Step-by-step explanation:
y = 4x 
(4 times a number. Ex: x could be 98740757 or 2, it doesn't matter.)
1 b = 4 o
3 b = 12 o
22 - 3 = 19 b
19 b = 76 o (more)
22 b = 88 o (total)
