My question concerns combining of "like" terms.
*Example(s) from my textbook.
*4x+x=5x.
*2ab+ab=3ab; and not 3a2b.
In a later section; the distribution principle;
*x2+5x/x(+x)=x+5+x=2x+5.
I thought in the combining of like terms that variables that have coefficients (both sides - like"b" in above example) (x = 1x) of one(1) - stays as it is - the 1 is not added together(Why?). This is lack of instructions in my textbook that I have concluded.
