-(-2x +1)=9-14x explain

x = 5/8 = 0.625

Step-by-step explanation:

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  16x - 10  =   2 • (8x - 5)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    8x-5 = 0

Add  5  to both sides of the equation :

                     8x = 5

Divide both sides of the equation by 8:

                    x = 5/8 = 0.625

One solution was found :

                  x = 5/8 = 0.625

x = 10/16 or x = 5/8

Step-by-step explanation

Step 1: Distribute the negetive to the equation inside of the parentheses

2x - 1 = 9 - 14x

Step 2: Isolate the variable on either side (In this case, I'll subtract 2x from both sides and Subtract 9 from both sides)

- 10 = - 16x

Step 3: Divide by the number in front of the variable on both sides and simplify

x = 10/16 or x = 5/8

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
