Solve 2( 4x - 1) = 18

Mathematics

Answer:

<h3>x=2</h3>

Step-by-step explanation:

Simplifying

2(4x + 1) = 18

Reorder the terms:

2(1 + 4x) = 18

(1 * 2 + 4x * 2) = 18

(2 + 8x) = 18

Solving

2 + 8x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + 8x = 18 + -2

Combine like terms: 2 + -2 = 0

0 + 8x = 18 + -2

8x = 18 + -2

Combine like terms: 18 + -2 = 16

8x = 16

Divide each side by '8'.

x = 2

Simplifying

x = 2

The answer is 2.5

2 (4x - 1) = 18
8x - 2 = 18
8x = 20
x = 2.5

What is the actual slope of this line?
-BARSIC- [3]

Answer:

  -4

Step-by-step explanation:

The line has a "rise" between the two points of -4 units for a "run" of +1 unit. The slope is the ratio ...

  m = rise/run = -4/1 = -4.

The slope is -4.

_____

<em>Additional comment</em>

A "whole number" must be non-negative. Here, the slope is negative. If you're restricted to "a fraction or a whole number", then the appropriate answer is the fraction -4/1. We suspect that "integer" is meant where "whole number" is used.
