Question

1/3 (2 + 4) -6 = 2/3 (5 - z)​

Answer 1

11

Explanation:

You can simplify everything on the left side of the equation first.

1/3 (2 + 4) - 6 = -4

-4 = 2/3 (5 - z)

Multiply both sides by 3/2 (multiplying by the reciprocal of 2/3 gets rid of the fraction)

(3/2) * -4 = 2/3 (5 - z) * (3/2)

-6 = 5 - z

-11 = -z

z = 11
