Question

22x - y = -23 ( equation 1)
11x + 12y = 1 ( equation 2)
To find the value of x , you need to substitute _____ in equation 2. The value of x is ?

anonymous · Answer

you can solve the first one for $y$ and get $$y=22x+23$$ substitute that

anonymous · Answer

X = ( y-23)/22
X= ( y + 23)/22
Y= 22x + 23
Y= 22x - 23

The easiest way to solve it would be to multiply equation 2 by -2
11x + 12y = 1  * -2 = -22x -24y -=2
Now add this to equation1

22x - y = -23 ( equation 1) 
-22x -24y -=2 ( equation 2)

Adding the equations we get:

-25y = -25
y=1

Substituting this into equation 1 we get:
22x -1 = -23
22x  = -22
x = -1
