Question

1 . 4x+7y-6z+6y-9x.4x and ____ are like terms7y and ____ are like terms 2. 1/2s-(6u-9u)+1/10t+2s 1/2s and ____ are like terms 6u and ___ are like terms

Answer 1

Like terms

We know

Like terms: are terms whose variables are the same.

For the case

4x+7y-6z+6y-9x.

4x and -9x are like terms (their variable is x)

7y and 6y are like terms (their variable is y)



2. 1/2s-(6u-9u)+1/10t+2s

1/2s and 2s are like terms (their variable is s)

6u and -9u are like terms (their variable is u)
