Answer:
(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)
Answer:
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).
