Use the substitution method to solve the system of equations. Choose the correct ordered pair.
x + 3y = 9
y = x-5
A. (6,3)
B. (3,-2)
C. (1,-5).
D. (6,1)

D (6,1)

Step-by-step explanation:

When , it means we don't need to move the variables to the left side and right side. We can use to substitute into the first equation directly.

When x=6, we can substitute the value of x into any equation whatever you want. You can choose or . I choose is easier to get the value of y.

When x=6, substitute into

Hooray, now you have the value of x and y which are x=6 and y=1.

I hope you will understand the answer.

You can ask any question here if you still cannot get the point. Don't be shy.
