<span>We will call A to the number of hours traveled by Annie and B the number of hours travelled by Brian. Then Annie traveled 5 times plus 2 hours than Brian, that is
A = 5 * B + 2. And the total number traveled by both of them was 20, so: A + B = 20
Next step is solve both equations putting value of A in the second equation:
5 * B + 2 + B = 20 that is the same than:
6 * B = 18 and:
B = 3 then:
A = 5 * 3 +2
A = 17
The solution is Annie traveled 17 hours and Brian only traveled 3 hours.</span>
B.x=$6.40. You do 32÷5 to figure out what 1x equals and that's $6.40

Answer:
subtraction property of equality
Step-by-step explanation:
The second equation is arrived at by subtracting 5z from both sides of the first equation. The property that lets you do that without changing the values of the variable is ...
the subtraction property of equality
__
x +5z = 10
x +5z -5z = 10 -5z . . . . subtract 5z from both sides
x = 10 -5z . . . . . simplify
