Question

An equation is shown below:
4(x - 3) - 5(x + 1) = 3

Which statement shows a correct next step in solving the equation?

1) The equation can become 4x - 3 - 5x + 1 = 3 by applying the associative property of multiplication.
2) The equation can become 4x - 3 - 5x + 1 = 3 by applying the distributive property.
3) The equation can become 4x - 12 - 5x - 5 = 3 by applying the distributive property.
4) The equation can become 4x - 12 - 5x - 5 = 3 by applying the associative property of multiplication.

Answer 1

3

Answer 2

do you need an explanation?

Answer 3

Yeah, is the answer 3 though?

Answer 4

well the answer is 3 because well you have to distribute you know that. then you will get
4x - 12 - 5x - 5 = 3.

Distributive property: a(b + c) = ab + ac
Associative property: a + (b + c) = (a + b) + c

Answer 5

4(x - 3) - 5(x + 1) = 3
4x -12 - 5x -5 = 3

Answer 6

Oh, I see. Thank you :)
