What's the solution to the following system of equations?

−3x−9y=18
4x+3y=12

x=( , )
y=( , )

x = 6 and y = -4 or (6,-4)

Step-by-step explanation:

To solve the system, multiply an equation to create same coefficients for one variable. Then stack the equations and perform elimination to solve for each variable.

Multiply 4x + 3y = 12 by 3. It becomes 12x + 9y = 36.

 12x + 9y = 36

+-3x - 9y = 18

   9x        = 54

     x = 6

To solve for y, substitute x = 6 into one of the equations.

12(6) + 9y = 36

72 + 9y = 36

9y = -36

y = -4

your answer is d 2,500
