First, let's find the additive inverse of the linear expression within the second set of parentheses. To do so, we can distribute -1 into the second set of parentheses. When we do so, we multiply each term of that linear expression by -1.
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.
( 5.7x - 0.8)+( - 4.9 x+ 1.4)
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.
5.7 x -0.8&
(+) -4.9 x +1.4&
0.8 x +0.6&
Therefore, we get the following result.
(5.7x-0.8)-(4.9x-1.4) = 0.8x +0.6
