-x = 2 - 3x + 3
Combine like terms 2 and 3 on the right side.
-x = (2 + 3) - 3x
-x = 5 - 3x
Add 3x to both sides (-3x and 3x on the right side cancel).
-x + 3x = 5
2x = 5
Divide by 2 on both sides (This cancels out the 2 in the 2x).
(2x)/2 = 5/2
x = 5/2
Thus, x is equal to 5/2.
Answer:
-3/4
Step-by-step explanation:
3x+4y=12
get into y=mx+b form first (m is the slope, b is the intercept)
So, 4y=12-3x
Then y=(12/4)-(3/4)*x
So your m is -3/4
Since you said it must be parallel the slope is the same to ensure they never touch
