Answer:
Given the system of equations, what is the solution?
x + 3y = 5
x - 3y = -1
The answer is {(2, 1)}
x=2 and y=1
Step-by-step explanation:
We can find the solution in two ways,the first way is by term elimination the equations:
We can find x with the equation (3)
Now we can replace x=2 in the equation (1) to find y
Now, we have found x and y
x=2
y=1
The second way is clearing x from equation 1
Now, we can replace in the equation (2)
Now, we can replace y=1 in the equation (1), (2) or (4) to find x
We will use the equation (1)
We have verified that by the two forms x = 2 and y = 1
