9-4(2x-1)=45
Multiply -4 by 2x and -1
9-8x+4=45
Subtract 9 from both sides
-8x+4=36
Subtract 4 from both sides
-8x=32
Divide both sides by -8
Final Answer: x= -4

Answer:

x = -4

Step-by-step explanation:

First we multiply -4 and 2x to get -8x.

Then we  multiply -4 and -1 to get 4.

We then add 9 and 4 to get 13.

Your equation should now look like this: 13-8x= 45

We now subtract 13 on both sides to get 32.

Finally, we divide -8 and 32 to get our final answer:

x= -4
