We are given this expression:
[tex] 7x + 4x + 3-1 [/tex]
Now we will use concept of like terms here:
like terms are terms that have the same variables and powers.
Now in our expression 7x and 4x are like terms.
So on adding 7x and 4x we get 11x.
Also we have 3 and -1 like terms.
Combining 3 -1 , we have 2.
So answer is 11x +2 .
