Question

8. Fill in the missing reasons (one for each step).

Given: 3x -6y = 27; X=5
Prove: -2 = y
a. 3x-6y = 27; x = 5
b. 15-6y = 27
c. -6y = 12
d. y=-2
e. -2 = y

Answer 1

The answer would be B) 15-6y=27

Explanation:

Pull out like factors :

-12 - 6y = -6 • (y + 2)

Solve : y+2 = 0

Subtract 2 from both sides of the equation :

y = -2
