I don't know how to figure out the j value.

**drwls**, Monday, April 12, 2010 at 8:36pmMove the 'j' terms to one side and the constants to the other. This will result in

3j = -18

Divide both sides by 3 for the final answer.

4j + 8 = j + -10

Reorder the terms:

8 + 4j = j + -10

Reorder the terms:

8 + 4j = -10 + j

Solving

8 + 4j = -10 + j

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-1j' to each side of the equation.

8 + 4j + -1j = -10 + j + -1j

Combine like terms: 4j + -1j = 3j

8 + 3j = -10 + j + -1j

Combine like terms: j + -1j = 0

8 + 3j = -10 + 0

8 + 3j = -10

Add '-8' to each side of the equation.

8 + -8 + 3j = -10 + -8

Combine like terms: 8 + -8 = 0

0 + 3j = -10 + -8

3j = -10 + -8

Combine like terms: -10 + -8 = -18

3j = -18

Divide each side by '3'.

j = -6

Simplifying

j = -6
