Question

Plz help!

An equation is shown below:

-2(4x - 1) - 7 = 5

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

Answer 1

Let's simplify step by step.
-2(4x-1) - 7

Answer 2

Distribute
=(−2)(4x)+(−2)(−1)+−7
=−8x+2+−7

Answer 3

First distribute.
-4x + 2 - 7 = 5
Then combine like terms.
-4x - 5 = 5
Add five to both sides
-4x = 10
Divide by four to get X alone
X = -2.5


Get it?

Answer 4

A. The equation can become -2(4x - 1) = -2 by applying the distributive property.
B. The equation can become -2(4x - 1) = 12 by applying the addition property of equality.
C. The equation can become -2(4x - 1) = 12 by applying the commutative property of addition
D. The equation can become -2(4x - 1) = -2 by applying the subtraction property of equality.

Answer 5

Well than....That's a completely different ball park.

Answer 6

We could start by adding 7 to both sides, giving us
-2(4x - 10 = 12

Answer 7

Combine like terms
= -8x + 2 + - 7
= (-8x) + (2 + - 7)
= -8x + - 5

Answer 8

so that would be addition and that will be B, most likely. That help?

Answer 9

Answer
= -8x - 5

@Calvin3 I should think the answer to your question is B, an answer you get by adding 7 to both sides.

@Thehulk49 Yes we do, it's alright.
