Question

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

Answer 1

-1/3+2z=5/6 2z=5/6+1/3 z=7/6(1/2) Z=7/12 -2/3x+3/7=1/2 -2/3x=1/2-3/7 x=1/14(-3/2) X=-3/28

Answer 2

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

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

----------



`- (2)/(3) x + (3)/(7) = (1)/(2) \\ \\ - (2x)/(3) + (3)/(7) = (1)/(2) - (2x)/(3) = (1)/(2) - (3)/(7) \\ \\ - (2x)/(3) = (1)/(14) \\ \\ -2x = (1)/(14) * 3 \\ \\ x = (3)/(14 * -2) \\ \\ x = - (3)/(28) \\ \\`

The final result is: x = - 3/28 or x = -0.1071.
