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.
