Remember that only like terms can be combined. An expression in simplest form has no like terms and parentheses.
6.8x-5
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.
2.5x + 4.3x - 5
⇓
2.5x + 4.3x + ( - 5)
Remember that like terms — constant terms or terms with the same variable and the same exponent — can be combined. In this case, we have two x-terms and one constant. Only the x-terms can be combined. Let's simplify the expression!
