# How do you combine like terms in #(7a + 3b ) - ( 4a + 2b )#?

See a solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

Next, group like terms:

Now, combine like terms:

To combine like terms in the expression (7a + 3b) - (4a + 2b), you first distribute the negative sign across the terms inside the parentheses. This results in -4a - 2b. Then, you can combine like terms by adding or subtracting the coefficients of the same variables. In this case, you have -4a and -4a, which combine to give -7a. Similarly, you have 3b and -2b, which combine to give b. So, the simplified expression is -7a + b.
