Now, let's identify which, if any, terms can be combined. Remember, only like terms — constant terms or terms with the same variable — can be combined.
( -5x+ 4)+( - x + 1)
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.
& -5 x + 4
&+ - x + 1
& -6 x +5
Therefore, we get the following result.
(-5x+4)+-1(x-1)=-6x +5
