Difference of Expression

5a + 3b - 6c - (20 - 4b + 13c)

= 5a + 3b - 6c - 20 + 4b - 13c

= 5a + 3b + 4b - 6c - 13c - 20

= 5a + 7 b - 19 c - 20

In this question, you would be solving the expression by combining like terms.

Solve:

(5a + 3b - 6c) - (20 - 4b + 13c)

Distribute the negative to the variables inside the parenthesis.

5a + 3b - 6c - 20 + 4b - 13c

Combine like terms.

5a + 7b - 6c - 20 - 13c

5a + 7b - 19c - 20

You can't combine anymore like terms now, so your answer would be 5a + 7b - 19c - 20

Answer:

5a + 7b - 19c - 20
