For this one I usually put the functions over one another like if it was an addition problem
Let's break it down.
You spent $20. Plus the $1 tip.
20 - 1 = 19
$19 is how much you spent without the tip
The cost for the taxi ride itself is $3
19 - 3 = 16
$16 is how much you spent without the ride cost + tip
You spent $2 for every mile traveled.
16/2=8
You traveled 8 miles

You can cross multiply to get 4 * 21 = 7x
84 = 7x; divide both sides by 7
12 = x so the number 12 will go in the blank (12 girls)
Answer:
x = 48°
