Answer 1

A)2b - 6 = 8

2b = 8 + 6

2b = 14

b= 14/2

b= 7

b) 6c = 5c + 8

6c - 5c = 8

c= 8

c) 3d = 2d - 2

3d - 2d = - 2

d= - 2

d) 3e = e +4

3e - e = 4

2e = 4

e= 4/2

e= 2

e) 9 = g - 3

g - 3 = 9

g= 9 + 3

g= 12

f) 2 (h+1) = 6

2h + 2 = 6

2h = 6 - 2

2h= 4

h= 4/2

h= 2

g) 4 + 3k = 4k - 2

3k - 4k = - 2 - 4

- k = - 6(-1)

k= 6
