Question

Solve: 6 (z-2) = 2 (z+1) -6​

Answer 1

Step-by-step explanation:

6(z-2)=2(z+1)-6

6z-12=2z+2-6

6z-12=2z-4

6z-2z=-4+12

4z=8

z=8/4

z=2

Answer 2

Answer:

z = 2

Step-by-step explanation:

(6 • (z - 2)) -  (2 • (z + 1) -  6)  = 0

 

6 • (z - 2) -  (2z - 4)  = 0

Pull out like factors :

  4z - 8  =   4 • (z - 2)

4 • (z - 2)  = 0

    Solve :    4   =  0

Solve  :    z-2 = 0

Add  2  to both sides of the equation :  

                     z = 2
