z + (z - 6) - 2 = -10

Answer 1

z + (z - 6) - 2 = -10

z + z - 6 - 2 = -10

2z - 8 = -10

2z = -2

z= -1

1st step: Distribute the + inside the parenthesis

2nd step: Combine like terms

3rd step: Isolate the variable (z) eliminating -8

4th step: divide by 2 both side

Answer 2

Z + (Z - 6) = -10

2 Z - 6 = -10

+6 +6

2Z/2 = - 4/2

Z = - 2

Check: - 2 + (- 2 - 6) = - 10

Answer 3

z + (z - 6) - 2 = -10

z + z + (-6) - 2 = -10

2z - 8 = -10

2z - 8 + 8 = -10 + 8

2z = -2

2z/2 = -2/2

z = -1

Answer 4

Hello Wolfie;

2z - 8 = -10

2z = +8 - 10 = -2

z = -1
