Given the system of equations. Which of the {-5x+y=6 - - > y=5x+6 3x-y=14}

options represents the resulting equation after an equivalent expression for y is substituted into the second equation. 3x - (5x + 6) = 14 - 3x + 5x + 6 = 6 3 (5x + 6) - y = 14 - 3x (5x + 6) + y = 6

The first thing we must do is solve the problem step by step to choose the correct option.

Step 1:

Clear y from the first equation:

-5x + y = 6

y = 5x + 6

Step 2:

Replace this value of y in the second equation:

3x-y = 14

Substituting:

3x - (5x + 6) = 14

answer

the resulting equation after an equivalent expression for y is substituted into the second equation is

3x - (5x + 6) = 14
