Answer 2

Step-by-step explanation:

Given:

$4a - 7b + 9c - 2a + 3b - c - 5a + 7a + 8c$

To find: Evaluate the expression.

Solution:

Tip: Add and subtract similar terms.

Step 1: Put the terms with a,b and c in different groups

$\red{4a - 2a - 5a + 7a} \green{ - 7b + 3b} \orange{ + 9c - c + 8c}$

Step 2: Add/subtract the terms having a together and same for b and c

$\red{11a - 7a} \green{ -4 b} \orange{ + 17c - c }$

or

$\red{4a} \green{ -4 b} \orange{ + 16c }$

Final answer:

$\bf 4a - 7b + 9c - 2a + 3b - c - 5a + 7a + 8c\\ \bf = 4a - 4b + 16c$

Hope it helps you.
