Often real life algebra problems look like the following: • 7+2+3−6+ 2 = 14 • It is difficult to even try to start solving a problem so large. I can't get my head around why something should be negative or positive or added or subtracted. In this lesson you will learn how to add linear expressions with rational coefficients by combining like terms. As I modeled identifying like terms I will use different colors to circle or underline the like terms. When combining like terms, such as 2x and 3x, we add their coefficients. In simple addition we learned to add all the numbers together to get a sum. Both terms have an x with no exponent, so we add their coefficients to get -6x.
