4j+8=j10
I don't know how to figure out the j value.

Move 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.

Simplifying
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
