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

9514 1404 393

  4x - 3(12x + 4) = -6

Step-by-step 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

44

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
