3x-7 / 4x + 2 = 3x + 14 / 4x-13

x =  0.5

Step-by-step explanation:

to solve this 3x-7 / 4x + 2 = 3x + 14 / 4x-13

solution

3x-7 / 4x + 2 = 3x + 14 / 4x-13

by adoting the cross multiplication method

4x - 13 ( 3x - 7 ) = 4x + 2 ( 3x + 14)

4x ( 3x - 7) - 13 ( 3x -7) = 4x( 3x + 14) +2( 3x + 14)

12x² -28x -39x +  91 = 12x² +  56x +6x + 28

combine the like terms and evaluate

12x² - 12x² - 28x  - 56x - 39x = 28 - 91

-123x = -63

divide both sides by the coefficient of x which is -123

-123x/-123 = -63/-123

x =  0.5

the correct is answer is a 9-sided polygon!
