Answer:
19/6n - 7/2
Step-by-step explanation:
4n - 5/6n - 4 + 1/2
4 = 24/6
24/6 - 5/6
19/6
-4 = -8/2
-8/2 + 1/2
-7/2
19/6n - 7/2
Answer:
y = 2x - 4
Step-by-step explanation:
Can I ask which variable you are solving?
PS I will assume you need the formula y=mx+b
-2x + y = - 4
Here you would translate the m and x variables to the right side making them positive.
y = 2x - 4
Now the formula is in proper form
