Solve the following problem using the elimination method:
-3x + 7y = 12
x - 2y = -3


Sagot :

Answer:

(3, 3)

Step-by-step explanation:

do you need to show your work or just the answer?

-3x+7y=12                                   mulitply both sides by 3 of the bottom.

x-2y=-3

-3x+7y=12                    

3x-6y=-9           < which turns into this

Then you have to sum the equations (vertically) to eliminate one variable.

y=3

Then substitute the given value of "y" into the equation

x-2 * 3=-3    then solve the equation for x      (x=3)

y=3   x=3    (3, 3)

*Check your answers.

-3*3+7*3=12

3-2*3=-3

12=12

-3=-3

(-3, -3)
