Question

Group the like terms together​
$4x,-3y,-x,\frac{2}{3}x,\frac{4}{5}y\text{and}y$

Answer 1

The terms having the same literal coefficients are called like terms. They may differ only in their numeral coefficients
Given terms:$4x,-3y,-x,\frac{2}{3}x,\frac{4}{5}y\text{and}y$
Here, $4x,-x,\frac{2}{3}x$ are like terms , as each has the same literal coefficient ${}^{\prime }{x}^{\prime }$
Here,$-3y,\frac{4}{5}y$ are like terms as each having the same literal coefficient$y$

Therefore, like terms in the group are $4x-x,\frac{2}{3}x\text{and}-3y,\frac{4}{5}y,y$.
