Answer:
4(x + 1)
Explanation:
The first step to simplifying this expression would be combining like terms:
3x + 1x + 5 - 1 = (3 + 1)x + 4 = 4x + 4
Now from here, it is possible to simplify this expression further. 4x and 4 both have a factor of 4, so we can factor out 4 like this:
4x + 4 = 4(x + 1)
And now we have simplified the expression.
I hope you find my answer and explanation helpful. Happy studying. :)
