Use the elimination method to solve the systems of equations choose the correct ordered pair 3x+6y=36 3x-6y=0

(6, 3)

Step-by-step explanation:

Given the 2 equations

3x + 6y = 36 → (1)

3x - 6y = 0 → (2)

Add the 2 equations term by term to eliminate the y- term

(3x + 3x) + (6y - 6y) = (36 + 0)

6x = 36 ( divide both sides by 6 )

x = 6

Substitute x = 6 into either of the 2 equations and solve for y

(1) : 18 + 6y = 36 ( subtract 18 from both sides )

6y = 18 ( divide both sides by 6 )

y = 3

Solution is (6, 3)

the solution is (6, 3)

Step-by-step explanation:

Subtract the second equation from the first, as indicated:

 3x+6y=36

-( 3x-6y=0)

      12y = 36.  Then y = 36/12 = 3.  

Subbing 3 for y in the second equation, we get 3x - 6(3) = 0, or 3x = 18, or x = 6.

Thus, the solution is (6, 3).

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
