-1/3+2z=-5/6 what does z equal? -2/3x+3/7=1/2 what does x equal?

Answers

$- (1)/(3) + 3z = - (5)/(6) \n \n 2z - (1)/(3) = - (5)/(6) \n \n 2z = - (5)/(6) + (1)/(3) \n \n 2z = - (1)/(2) \n \n = - (1)/(2 * 2) \n \n z = - (1)/(4) \n \n$

The final result is: z = - 1/4 or z = -0.25.

Answer:

14 = 14

Infinite solutions

Step-by-step explanation:

First, you substitute x with 4.

So: 4 + 10 = 4 times 4 - 2

14 = 16 - 2

14 = 14

14 = 14 or infinite solutions
