Answer:
Answer C. x = 2
Step-by-step explanation:
Given:
x − 2y = 2
3 * ( x ) + y = 6
You need to group the x-coordinates of the system of equations.
Rewrite x − 2y = 2 , in such a way that it starts with x =...
x = 2y + 2
Substitute x = 2y + 2 in 3 * ( x ) + y = 6, which gives:
3 * ( 2y + 2 ) + y = 6
6y + 6 + y = 6
7y = 0
y = 0
Substitute y = 0 in x = 2(y) + 2 gives x = 2*0 + 2
So x = 2, which is answer C.
x - 6x + 2x - 2x
x - 6x + 0
-5x
X= -2 or X=9
Distribute the x to the (x-9) and then move all the x values to one side and the constants to the other and then solve until you have x by its self. You should get two answers that work.
