Question

What is the value of the x variable in the solution to the following system of equations?

4x + y = 8
x − 2y = 2

0

2

There is no x value as there is no solution to this system

x can be any value as there are infinitely many solutions to this system

Answer 1

double everything in equation 1 to go from

4x + y = 8

to

8x + 2y = 16

Answer 2

so you now have this system

8x + 2y = 16
x − 2y = 2

add the two equations to get

8x + 2y = 16
x − 2y = 2
------------
9x + 0y = 18


9x = 18


I'm sure you know what to do from here.
