Answer:
Like terms are those terms which have same variable to the same power.
In the given expression:
[tex]4x-3+7x+1[/tex] .....[1]
here, x is the variable
by definition of like terms;
4x and 7x are like terms
Constant term 3 and 1 are also like terms;
then;
Combine like terms in [1] we have;
[tex](4x+7x)+(-3+1)[/tex]
Simplify:
[tex]11x-2[/tex]
Therefore, we get the result [tex]11x-2[/tex]
