Answer:
x = 1
Step-by-step explanation:
4(2x + 1) - 3 = - 3(x - 4) ← distribute parenthesis on both sides
8x + 4 - 3 = - 3x + 12
8x + 1 = - 3x + 12 ( add 3x to both sides )
11x + 1 = 12 ( subtract 1 from both sides )
11x = 11 ( divide both sides by 11 )
x = 1
The slope of a line parallel to the line whose equation is 6x + y = -3 is: -6.
<h3>How to Find the Slope of a Line?</h3>
When given an equation of a line, the slope (m) of the line can easily be determined if the equation is written in the slope-intercept form. The slope-intercept form of the equation of a line is expressed as: y = mx + b.
The "m" in the equation is the slope of the line.
The slope of two lines that are parallel to each other are always the same.
Rewrite the equation, 6x + y = -3
y = -3 - 6x
y = -6x - 3
The slope in 6x + y = -3 is -6. The line that is parallel to the line would also have the same slope.
Therefore, the slope of a line parallel to the line whose equation is 6x + y = -3 is: -6.
