Question

Which expression is equivalent?

7 − 4(2x − 3)
A) 8x + 5
B) 8x − 19
C) −8x + 5
D) −8x + 19

Answer 1

It’s answer D because when you slave it you will get -8x+19

Answer 2

D.

Explanation:

First, we expand the expression using the rule:

`x(y - z) = xy - xz`

`7 - (4 * 2x)- ( - 4 * 3)`

Double negative = Positive

`7 - (4 * 2x) + (4 * 3)`

`7 - 8x + 12`

`- 8x + 19`

The answer is D.
