Answer 1

a) x - 2 = -6

x = -6 + 2

x = -4

b) 2x - 3 = 11

2x = 14

x = 7

c) 2x/3 = 4

2x = 12

x = 6

d) 2x/4 = 3/4

2x = 3

x = 3/2

x = 1,5

e) 2x + 2/5 = 4

2x + 2 = 20

2x = 18

x = 9

f) 6/4 = x + 1

6 = 4x + 4

2 = 4x

x = 2/4 = 1/2

g) 6/5 = x+1/2

12/5 = x+1

12 = 5x+5

5x = 7

x = 7/5

h) 3/4 = (2x + 1)/2

3 = 8x + 4/2

3 = 4x + 2

5 = 4x

x = 5/4 = 1,25
