Question

Which order pair represents the solution to the system of linear equations?
y=x+2
y=2x+1
A. (-1,1)
B. (1,3)
C. (1,2)
D. (2,1)

Answer 1

Answer:

(1,3)

Step-by-step explanation:

1) since both equations are equal to "y" we can solve by substitution

X+2=2x+1

Bring "x" to the right ans "1" to the left

1=x

Since we have the value of "x" we can plug it into the original equation to get "y"

Y=x+2

Y=1+2

Y=3

So

(1,3) is the answer

Answer 2

B. (1,3) is the correct answer to your solution.
