Question

6j + 7 =21 -j pls show work​

Answer 1

j = 2

Explanation:

6j + 7 = 21 - j

6j + j = 21 - 7

7j = 14

j = 14/7

j = 2

Answer 2

Explanation:

6j + 7 = 21 - j

Add 'j' to both sides

6j + 7 + j = 21 - j +j

7j + 7 = 21

Subtract 7 form both sides

7j + 7 - 7 = 21 - 7

7j = 14

Divide both sides by 7

7j/7 = 14/7

j = 2
