6=2 (w-4)

and different problem

(2n-8) (-2) = - 24

and this problem

(2z+6) (3) = 33 and this one last one - 4 (-2b-7) = 44

1) 6=2 (w-4)

Divide both sides by 2.

3=w-4

Add 4 to both sides.

7=w

2) (2n-8) (-2) = - 24

Divide both sides by - 2.

2n-8=12

Add 8 to both sides.

2n=20

Divide both sides by 2.

n=10

3) (2z+6) (3) = 33

Divide both sides by 3.

2z+6=11

Subtract 6 from both sides.

2z=5

Divide both sides by 2.

z = 2.5

4) - 4 (-2b-7) = 44

Divide both sides by - 4.

-2b-7=-11

Add 7 to both sides.

-2b=-4

Divde both sides by - 2.

b=2
