X + 4y - 12 = 0 x = 3y - 7 Which of the following is the resulting equation?

-7y - 19 = 0

y - 5 = 0

7y + 19 = 0

7y - 19 = 0

The answer to your question is 7y - 19 = 0

Step-by-step explanation:

Data

Equation l x + 4y - 12 = 0

Equation ll x = 3y - 7

Process

1. - Substitute equation ll in equation l

3y - 7 + 4y - 12 = 0

2. - Group like terms

(3y + 4y) + (-7 - 12) = 0

3. - Simplify like terms

7y - 19 = 0

4. - Result

7y - 19 = 0
