Answer:
-23
Explanation:
3.5 (x+20) = 6 + .75 (x+1)
First off you'll have to distribute the x values, leaving....
3.5x + 70 = 6 + .75x + .75
Now you have to simplify,
3.5x + 70 = 6 + .75x + .75
- 6 - 6
3.5x + 64 = .75x + .75
Here we can now get rid of the .75
3.5x + 64 = .75x + .75
- .75 -.75
3.5x + 63.25 = .75x
To get rid of the last x value we subtract from both sides;
3.5x + 63.25 = .75x
-3.5x -3.5x
63.25 = -2.75x
Then divide to isolate the variable.
63.25 ÷ -2.75
to get -23 as the answer.
Sorry this is really long, but hopefully it helps! Have a great day!
