Answer 2

Answer 3

Distribute -2 into the first parenthesis by multiplying it to every term:

\(-2(-5t + 1) \rightarrow -2 \times -5t + -2 \times 1\)

Answer 4

Okay, so do I solve that equation right there?

Answer 5

Just multiply:

-2 * -5t

-2 * 1

Can you multiply those?

Answer 6

10t and -2, right?

Answer 7

Yep!

That gives us:

\(10t - 2 + 2(-6 - 4t)\)

Now we distribute 2 into the parenthesis.

2 * -6 = ?

2 * -4t = ?

Can you multiply those?

Answer 8

-12 and -8t

Answer 9

Yep, so we have:

\(10t - 2 - 12 - 8t\)

Now combine like terms:

\(10t - 8t\)

\(-2 - 12\)

Subtract those.

Answer 10

2t and -14

Answer 11

Yep, so your final answer is \(2t - 14\).
