-6z-18=-114 someone know this problem?

- 6z - 18 = - 114

multiply each side by (- 1)

6z + 18 = 114

(6z + 18) - 18 = (114) - 18

6z = 114 - 18

6z = 96

(6z) / 6 = (96) / 6

z = 16 ⇦ answer

*******

-6z-18=-114
6z+18=144
6z=126
z=21

:)

6z + 18 = 114

6z = 96

z = 16

- 6z - 18 = - 114
- 6z = - 96
z = 16.

-6z - 18 = -114
-6z = 18 - 114
z = -96/(-6)
z = 16

-6z = -114+18
-6z = -96
z= (-96) / (-6) = 16

Answer:
- 6z - 18 = - 114
- (6z + 18) = - (114)
6z + 18 = 114
6z = 114 - 18
6z = 96
z = 96 / 6
z = 16

-6z-18=-114
-(6z+18)=-114
6z+18=114
6z=114-18
6z=96
z=96/6
z=16
