Which pairs are like terms in expression 2/5y + 1/5x - 0.2y - 6 + (-2)

The pair of like terms are:

Solution:

Given expression is:

We have to find the pairs that are like terms in the given expression

Like terms means that, terms that have same varibale but different ( or same ) coefficients

Here in the given expression "x" and "y" are the two variables present

Arrange the like terms

So here the first two terms has same varibale "y" but different coefficients. So they form a pair of like terms

"x" is present only once . There is no other term with variable "x"

6 and -2 are constants

So the pair of like terms are:

y = x + 95

y = 42 + 95

y=137 mm hg
