Exercise 17 Page 95

Remember that only like terms can be combined. An expression in simplest form has no like terms and parentheses.

11x+2

Practice makes perfect
An expression in simplest form has no like terms and parentheses. Let's first rewrite this expression as a sum to identify all like terms. 11x + 9 - 7 ⇓ 11x + 9 + ( - 7) Remember that like terms — constant terms or terms with the same variable and the same exponent — can be combined. In this case, we have one x-term and two constants. We will combine like terms to simplify the expression.
11x+9+(- 7)
11x+9-7
11x+2
