What is the solution to the system of equations?

A) (1, 4)

B) (4, 1)

C) (7, 4)

D) (2.5, 5.5)

Answers

If you would like to solve the system of equations, you can do this using the following steps:

x = y - 3
x + 3y = 13 ... y - 3 + 3y = 13
___________
y - 3 + 3y = 13
4y = 13 + 3
4y = 16
y = 4

x = y - 3 = 4 - 3 = 1

(x, y) = (1, 4)

The correct result would be A) (1, 4).

when you see the sign facing the "y" the line is the minimum value
when you see the sign not facing the"y" the lin is the maximum value

When ever you see the sign facing the "y" the line will be minimum value for the next one
whenever you see the sign not facing the "y" the line will be maximum value
