Question

Use the substitution method to solve the system of equations. Choose the correct ordered pair.

Y=6x-4
y=7x-7
A. (3,14)
B. (4,18)
C. (2,11)
D. (5,9)

Answer 1

The correct answer A

Answer 2

A) (3,14)

Explanation:

6x - 4 =7x - 7

subtract 6x from both sides

-4 = x -7

add 7 to both sides

3= x

now that we know the value of x, plug it into either equation to get y=14
