Question

How do I solve 4(x+3)-(x-1)=40

Answer 1

The answer is: x = 9

Here's how I got my answer:

Step 1: Simplify the brackets. Which leaves us with
`4(x+3)-x+1=40`

Step 2: Expand it. Which leaves us with
`4x+12-x+1=40`

Step 3: Simplify
`4x+12-x+1` to
`3x+13`. Which leaves us with
`3x+13=40`

Step 4: Subtract 13 from both sides. Which leaves us with
`3x=40-13`

Step 5: Simplify
`40-13` to 27. Which leaves us with
`3x = 27`

Step 6: Divide both sides by 3, leaving us with our answer, x = 9.

Answer 2

`4(x+3)-(x-1)=40\\\\ 4x+12-x+1=40\\\\ 3x=27\\\\ x=9`
