To solve the problem we must know about Like Terms.

<h3>What are Like Terms?</h3>

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

The solution to the problem is (-1.7x-1.3).

Given to us

  • f(x) = 3.7 - 2x
  • g(x) = 0.25x - 5

To find

f(x) + g(x)

To solve the problem we will put the functions as given to us,

f(x)+g(x)\\= ( 3.7 - 2x)+( 0.25x - 5)

Open brackets,

=3.7 - 2x+ 0.25x - 5

<h3>Like Terms</h3>

Solve the like terms,

=3.7 - 2x+ 0.25x - 5\\\\=0.25x-2x-5+3.7\\\\=-1.75x-1.3

Hence, the solution to the problem is (-1.7x-1.3).
