Step 1
Like terms in an expression are terms that are exactly alike. Either they are constants(for example 8), variables( for example x ) or a combination of variables and constants ( for example 3x)
Step 2
Draw a conclusion from step 1
The given expression is 3x + 8 + 8x
The like terms here are therefore 3x and 8x because they are alike, consisting of a variable and a coefficient or constant.
