anonymous · Answer

no

igreen · Answer

Like terms are the numbers/letters that are the same.

Like in 5 + x + z + 2x

x and 2x are like terms, because they both have 'x' as their variable.

Simplify the following expression:

anonymous · Answer

a + 2c - 5b - c + a - b 
= a + a - 5b - b + 2c - c 
= 2a - 6b + c

igreen · Answer

No.

The like terms are:

a and a

2c and -c

-5b and -b

Simplify them by adding/subtracting:

a + a = 2a

2c - c = c

-5b - b = -6b

So we have -6b + 2a + c
