Question

2.(06.01)

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second
equation
12x - y = -4
4x - 3y = -6 (1 point)

Answer choices
4x - 3(-12x - 4) = -6

4x - 3(12x + 4) = -6

4(12x + 4) - 3y = -6

4(-12x - 4) - 3y = -6

Answer 1

9514 1404 393

Answer:

4x - 3(12x + 4) = -6

Explanation:

Solving the first equation for y, you have ...

12x +4 = y . . . . add y+4 to both sides

Replacing y with (12x+4) in the second equation gives ...

4x -3(12x +4) = -6 . . . . matches the second choice
