Answer 1

Question:

Solve the following equation: - 3(x+4)=-5x

Solution:

Consider the following equation:

$-3(x+4)=\text{ -5x}$

This is equivalent to:

$-3x\text{ -12 = -5x}$

now, joining similar terms we get:

$-3x\text{ + 5x = 12}$

this is equivalent to:

$2x\text{ = 12}$

solving for x:

$x\text{ = }\frac{12}{2}=\text{ 6}$

then, we can conclude that the correct answer is:

$x\text{ = 6}$
