Answer:
x = -2/4
Step-by-step explanation:
You always want to leave the variable alone-
-4x + 7 = 9
To do that you need to get rid of the seven and that can be done by subtracting/adding it by its opposite value in both sides of the equation.
-4x = 2
Get rid of that 4 by dividing from both sides of the equation-
x = -2/4
Answer:
x= -1/2
Step-by-step explanation:
Mkay... You would start off by getting rid of the parentheses because they aren't needed here...
7 - 4x = 9
Now, you would add 4x to both sides to get rid of the subtraction...
7 = 9 + 4x
Then, you subtract 7 from each side....
0 = 2 + 4x
Moving on, you would subtract 2 from each side...
-2 = 4x
And then divide 4 on each side to get...
x = -1/2
And there's your answer!
