4. What is the value of x in this equation? 3(2x - 5) - 4x + 8= -1

x= 3

Step-by-step explanation:

Simplify the equation:

3(2x-5)- 4x+8= -1 becomes 6x-15-4x+8= -1

Then, combine like terms.

6x-4x= 2x

-15+8= -7

So now your equation becomes 2x-7= -1

Now, we need to isolate our variable (x).

Add 7 to both sides.

-7+7 cancels out and -1+7= 6

and now you have 2x=6

To solve for x, you need to divide by 2 on both sides and you get an answer of 3.

x= 3
