The first step in simplifying this expression is to identify which, if any, terms can be combined. Remember, only like terms — constant terms or terms with the same variable — can be combined.
( x -10)+( 3x -6)
In this case, we have two x-terms and two constants. Let's arrange the like terms in columns. Then, let's perform the addition.
& x - 10
&+ 3 x - 6
& 4 x - 16
Therefore, we get the following result.
(x-10)+(3x-6) = 4x-16
