Question

5x-7(2-4x)
And can you explain how you got the answer

Answer 1

FOIL / Distribute

Leave 5x alone for now.
-7(2-4x) = -7*2 and -7*-4x = -14+28x
Add in 5x -> 5x - 14 + 28x

Answer 2

But what is the rule when you do it for any problem like that

Answer 3

You expand the equation in any way possible until it cannot be expanded. -7(2-4x) can be expanded into -14+28x through distribution. After that, nothing else can be expanded.

Answer 4

Ohhh Thank you
