===> Exercise 1

  • 3k − 8 = 7

Add 8 to both sides.

  • 3k = 7 + 8

Add 7 and 8 to get 15.

  • 3k = 15

Divide both sides by 3.

  • k = 15 / 3

Divide 15 by 3 to get 5.

  • k=5 ===> Answer

===> Exercise 2

  • 8b + 9 = −15

Subtract 9 from both sides.

  • 8b= −15 − 9

Subtract 9 from −15 to get −24.

  • 8b = −24

Divide both sides by 8.

  • b = -24 / 3

Divide −24 entre 8 para obtener −3.

  • b=−3 ===> Answer

===> Exercise 3

  • 8 = 3x − 13

Swap the sides so that all the terms of the variables are on the left side.

  • 3x −13 = 8

Add 13 to both sides.

  • 3x = 8 + 13

Add 8 and 13 to get 21.

  • 3x = 21

Divide both sides by 3.

  • x = 21 / 3

Divide 21 by 3 to get 7.

  • x = 7 ===> Answer

===> Exercise 4

  • 6p + 22 = 4

Subtract 22 from both sides.

  • 6p = 4 − 22

Subtract 22 from 4 to get −18.

  • 6p = −18

Divide both sides by 6.

  • p = -18 / 6

Divide −18 entre 6 para obtener −3.

  • p = −3 ===> Answer

===> Excercise 5

  • 84 = 51 + 11c

Swap the sides so that all the terms of the variables are on the left side.

  • 51 + 11c = 84

Subtract 51 from both sides.

  • 11c = 84 − 51

Subtract 51 from 84 to get 33.

  • 11c = 33

Divide both sides by 11.

  • c = 33 / 11

Divide 33 by 11 to get 3.

  • c = 3 ===> Answer

Solution 1 :-

>> 3k - 8 = 7

>> 3k = 7 + 8

>> 3k = 15

>> k = 15 / 3

>> k = 5

Solution 2 :-

>> 8b + 9 = -15

>> 8b = -15 - 9

>> 8b = -24

>> b = -24 / 8

>> b = -3

Solution 3 :-

>> 8 = 3x - 13

>> 3x = 13 + 8

>> 3x = 21

>> x = 21 / 3

>> x = 7

Solution 4 :-

>> 6p + 22 = 4

>> 6p = 4 - 22

>> 6p = -18

>> p = -18 / 6

>> p = -3

Solution 5 :-

>> 84 = 51 + 11c

>> 11c = 84 - 51

>> 11c = 33

>> c = 33 / 11

>> c = 3
