Simplify the expression: 2(a -3) + 4b - 2(a -b -3) + 5

Question

Simplify the expression: 2(a -3) + 4b - 2(a -b -3) + 5

Answer 1

Hi Maki!

Make sure you use PEMDAS when simplifying this expression.

2(a-3) + 4b -2(a -b -3) + 5

Let's start off by distributing the outside coefficient to the parentheses:

2a - 6 + 4b -2a +2b +6 +5

Now, let's take care of adding/subtracting like terms:

2a and -2a cancel each other out and the 6 and -6 cancel each other out, leaving us with the final answer:

6b + 5

Hope this helps!

Answer 2

2(a-3) +4b -2(a-b-3) +5

= 2a-6+4b -2a+2b+6+5

= 6b +5
