Question

Combine like terms to write an equivalent expression. Then complete the statements.

9 + j + 6j – 1 – 2k

 

The constants, 1 and 21 and 99 and 69, 6, 1, and 2, are like terms.

 

 

j and 6jj, 6j, and 2kj and 2k6j and 2k are like variable terms.

 

 

Combine the constant terms by adding 1 and 9adding 9 and 6subtracting 1 from 9subtracting 6 from 9.

 

 

Combine like variable terms by adding the coefficients, 1 and 6coefficients, 9 and 6variables, j and kvariables, 1 and 9.

 

 

The equivalent expression is 12jk15j – 3k7j – 2k + 85jk + 8.

 

Answer 1

1 and 9; j and 6j; subtracting 1 from 9; coefficients, 1 and 6; 7j-2k+8.
