Answer:
x = 1, y = -5.
Explanation:
X-3y = 16 Equation (1)
4x- y = 9 Equation (2)
We can solve this by the Method of Elimination.
One way is to multiply the second equation by -3, as follows:
-3(4x - y = 9)
= -12x + 3y = -27 Call this equation (3)
Now if we add equation (3) to equation (1) we eliminate the y terms:
x - 3y = 16
-12x + 3y = -27 Adding:
-11x + 0 = -11
-11x = -11
x = -11/-11 = 1
Finally, we find the value of y by substituting x = 1 into equation (2):
4(1) - y = 9
-y = 9 - 4
-y = 5
y = -5.
So, the answer is x = 1, y = -5.
or we can write it as an ordered pair (1, -5).
Hope this helps.
