Question

equations with variables on both sides , evaluate each equation 4 - 3j = 6j - 5 9d - 9 =3d - 3 f -4 = 6f + 26 -2k + 3 = 5k + 24 5a -3 = 8a + 6

Answer 1

1) 4 - 3j = 6j - 5

Collecting like terms, it becomes

- 3j - 6j = - 5 - 4

- 9j = - 9

j = - 9/- 9

j = 1

2)

9d - 9 = 3d - 3

Collecting like terms, it becomes

9d - 3d = - 3 + 9

6d = 6

d = 6/6

d = 1

3) f - 4 = 6f + 26

Collecting like terms, it becomes

f - 6f = 26 + 4

- 5f = 30

f = 30/- 5

f = - 6

4) - 2k + 3 = 5k + 24

Collecting like terms, it becomes

- 2k - 5k = 24 - 3

- 7k = 21

k = 21/- 7

k = - 3

5) 5a - 3 = 8a + 6

Collecting like terms, it becomes

5a - 8a = 6 + 3

- 3a = 9

a = 9/- 3

a = - 3
