Answer:
Solution (6 ,3).
Step-by-step explanation:
Given : 3x + 6y = 36 and 3x - 6y = 0
To find : use the elimination method to solve the system of equations.
Solution : We have given
3x + 6y = 36 ------(1)
3x - 6y = 0------(2)
_______________ (On adding both equations)
6x + 0 = 36 .
On dividng both sides by 6
x = 6.
On plug x = 6 in equation 1
3 ( 6) + 6y = 36.
18 + 6y = 36 .
On subtracting both sides by 18
6y = 36 - 18.
6y = 18
On dividing both sides by 6
y = 3
Solution (6 ,3)
Therefore, Solution (6 ,3).
