Question

Solve the following system of equations to find 𝑥.

  1. 6x3y=48 6x - 3y = -48
  2. 6x+9y=24 6x + 9y = -24

Group of answer choices:

  • x=3 x = 3
  • x=2 x = -2
  • x=2 x = 2
  • x=7 x = 7
  • x=7 x = -7

Solution

To solve the system of equations for x, follow these steps:

  1. Write down the system of equations:

    6x - 3y = -48 6x + 9y = -24

  2. To eliminate one of the variables, subtract the second equation from the first:

    (6x - 3y) - (6x + 9y) = -48 - (-24)

    This simplifies to:

    -12y = -24

  3. Solve for y by dividing both sides of the equation by -12:

    y = -24 / -12 = 2

  4. Substitute y = 2 into the first equation:

    6x - 3*2 = -48

    This simplifies to:

    6x - 6 = -48

  5. Add 6 to both sides of the equation to isolate 6x:

    6x = -48 + 6 = -42

  6. Divide both sides of the equation by 6 to solve for x:

    x = -42 / 6 = -7

So, the solution to the system of equations is x = -7.
