Question

X – 6y - 9 = 0 x = 8y + 6 What is a resulting equation?

14y + 3 = 0
2y – 15 = 0
-2y + 3 = 0
2y – 3 = 0

Answer 1

-2y + 3 = 0

Explanation:

x - 6y - 9 = 0

-6y - 9 = -x subtract x from both sides

6y + 9 = x divide both sides by -1

x = 8y + 6

6y + 9 = 8y + 6 replace x with 6y + 9

-2y + 9 = 6 subtract 8y from both sides

-2y + 3 = 0 subtract 6 from both sides
