4j+8=j-10

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
