Answer:
a = 4, b = 3
Step-by-step explanation:
Expand and simplify the given expression then compare coefficients of like terms.
a(bx + 5) - 2(bx + a)
= abx + 5a - 2bx - 2a
= (ab - 2b)x + 3a
Given that this expression is equal to 6x + 12
Comparing coefficients of like terms.
3a = 12 ( divide both sides by 3 )
a = 4
ab - 2b = 6 , that is
4b - 2b = 6
2b = 6 ( divide both sides by 2 )
b = 3
Thus a = 4 and b = 3

Hey there!
If there are 5 choices for a hairstyle, that means that there are 5 options per 1 eye color. This totals out to 15 options (3 × 5) total for eye color and hairstyle combinations.
For each of those combinations, there are an additional 7 options for an outfit. That means that there is a total of 105 options (7 × 15) available to choose from.
Hope this helped you out! :-)
