Question

Simplify, using the distributive property and then combining like terms.

5(3a+b)−2(3a+b)

Answer 1

The final answer would be
`9a + 3b` .

Explanation:

Solve the following equation:

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

Use Distributive Property:

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

`15a + 5b - 6a - 2b`

-Combine
`15a` and
`6a`:

`15a + 5b - 6a - 2b`

`9a + 5b - 2b`

-Combine
`5b` and
`-2b`:

`9a + 5b - 2b`

`9a + 3b`

So, the answer is
`9a + 3b` .

Answer 2

9a + 3b

Explanation:

Given

5(3a + b) - 2(3a + b) ← distribute both parenthesis

= 15a + 5b - 6a - 2b ← collect like terms

= 9a + 3b
