Answer 1

1. 2a - 3 = a +1/-a+3

2a - a = 1 + 3

1a = 4/:1

a=4

 

2. 4b + 3 = 3b - 4/-3b-3

4b - 3b = -4-3

1b = -7/:1

b = -7

 

3. 7 + 3c = -5 + 2c/-2c-7

3c + 2c = -5 - 7

5 c = 12/:5

c = 2,4

 

4. 5d + 2 = 3d/-3d-2

5d - 3d = -2

2d = -2/:2

d = -1

 

5. 6e - 7 = 9e +5/-9e +7

6e - 9e = 5 + 7

-3e = 12/:(-3)

e = -4

 

6. 6f - 1 = f + 2/-f +1

6f - f = 2 +1

5f = 3/:5

f = 0,6
