6x + 11 = 21
Help I’m on a quiz and this question is so confusing

Step by Step Solution

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    6*x+11-(21)=0  

Step by step solution :

Pulling out like terms

1.1     Pull out like factors :

  6x - 10  =   2 • (3x - 5)

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  :    3x-5 = 0  

Add  5  to both sides of the equation :  

                     3x = 5

Divide both sides of the equation by 3:

                    x = 5/3 = 1.667

One solution was found :

x = 5/3 = 1.667

i think the length is 12 and the width is 17
