Question

What is the x-coordinate of the solution of the following system of equations?

3x + y = 6

x - y = 6

a)-3
B)0
c)3

Answer 1

x=3

Answer 2

Well, this is not a hard question. You need not solve for \(y\)... just eliminate \(x\).

Answer 3

Add both equations, and then solve for \(x\).

Answer 4

add the two equations
4x=12
x=3

Answer 5

After adding both equations, you'd get the following:\[3x + x = 6 + 6\]

Answer 6

A hate these cause all the giant words and how they put it confuses me o.o

Answer 7

Now, you need to solve that equation to get the \(x\)-coordinate.
Got it?
