Answer: 3,840 miles
Step-by-step explanation:
320x12=3,840
a. The solution is (0,2)
b. The first expression will be easier to substitute as in the first expression the variable y is already isolated on one side of the equation so we can easily put 5x+2 in place of y in equation 2.
Step-by-step explanation:
Given equations are:

a. Solution
Putting y = 5x+2 in equation 2

Putting x = 0 in equation 1

Hence,
The solution is (0,2)
b: Reason:
The first expression will be easier to substitute as in the first expression the variable y is already isolated on one side of the equation so we can easily put 5x+2 in place of y in equation 2.
