Heres a tough math problem, 2((3(-2)+4)+5(x-3))-2((x-6+4)+5x-15 Can you solve it?

I'm learning how to simplify and this was an example on the worksheet we were given. It showed me how to get the answer step by step and I still didn't get it. Don't worry, answering this will not be giving me the answer to any homework I have. This was just an example. See if you can figure it out and get the same answer that I saw. Impossible? Possible? Give it a try. Tell me what you think of it as well. Is my teacher crazy giving us this? Comments please! Your opinion is important!

Simplifying

2(3(-2) + 4) + 5(x + -3) + -2(x + -6 + 4)

Multiply 3 * -2

2(-6 + 4) + 5(x + -3) + -2(x + -6 + 4)

Combine like terms: -6 + 4 = -2

2(-2) + 5(x + -3) + -2(x + -6 + 4)

Multiply 2 * -2

-4 + 5(x + -3) + -2(x + -6 + 4)

Reorder the terms:

-4 + 5(-3 + x) + -2(x + -6 + 4)

-4 + (-3 * 5 + x * 5) + -2(x + -6 + 4)

-4 + (-15 + 5x) + -2(x + -6 + 4)

Reorder the terms:

-4 + -15 + 5x + -2(-6 + 4 + x)

Combine like terms: -6 + 4 = -2

-4 + -15 + 5x + -2(-2 + x)

-4 + -15 + 5x + (-2 * -2 + x * -2)

-4 + -15 + 5x + (4 + -2x)

Reorder the terms:

-4 + -15 + 4 + 5x + -2x

Combine like terms: -4 + -15 = -19

-19 + 4 + 5x + -2x

Combine like terms: -19 + 4 = -15

-15 + 5x + -2x

Combine like terms: 5x + -2x = 3x

-15 + 3x
