Which equation is equivalent to [tex]2x - 4(2x - 8) = 5x[/tex]?

A. [tex]-6x - 8 = 5x[/tex]

B. [tex]-4x + 32 = 5x[/tex]

C. [tex]-6x + 32 = 5x[/tex]

D. [tex]-4x + 16 = 5x[/tex]



Answer :

To determine which equation is equivalent to the given equation [tex]\( 2x - 4(2x - 8) = 5x \)[/tex], follow these steps:

1. Start with the original equation:
[tex]\[ 2x - 4(2x - 8) = 5x \][/tex]

2. Simplify the left-hand side by distributing the [tex]\(-4\)[/tex] across the terms within the parentheses:
[tex]\[ 2x - 4(2x - 8) = 2x - 4 \cdot 2x + 4 \cdot 8 \][/tex]
Simplify the multiplication inside:
[tex]\[ 2x - 8x + 32 \][/tex]

3. Combine like terms on the left-hand side:
[tex]\[ 2x - 8x + 32 = -6x + 32 \][/tex]

4. Rewrite the simplified equation:
[tex]\[ -6x + 32 = 5x \][/tex]

At this point, the simplified version of the given equation is [tex]\(-6x + 32 = 5x\)[/tex].

Let's match this to the provided options:
1. [tex]\( -6x - 8 = 5x \)[/tex]
2. [tex]\( -4x + 32 = 5x \)[/tex]
3. [tex]\( -6x + 32 = 5x \)[/tex]
4. [tex]\( -4x + 16 = 5x \)[/tex]

The equation [tex]\(-6x + 32 = 5x\)[/tex] matches option 3.

Thus, the equivalent equation is:
[tex]\[ \boxed{-6x + 32 = 5x} \][/tex]
