    Simplifying

    -7 + -0.75x = 14

    Solving

    -7 + -0.75x = 14

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

    Add '7' to each side of the equation.

    -7 + 7 + -0.75x = 14 + 7

    Combine like terms: -7 + 7 = 0

    0 + -0.75x = 14 + 7

    -0.75x = 14 + 7

    Combine like terms: 14 + 7 = 21

    -0.75x = 21

    Divide each side by '-0.75'.

    x = -28

    Simplifying

    x = -28

    First, get all the numbers without variables on the same side of the equation.

    -7 - 3/4x = 14

    You need to get rid of the seven, so if you add 7 to both sides, you can take care of it

    7 + (-7) - 3/4x = 7 + 14

    -3/4x = 21

    Now, you have to get rid of the 3/4 in front of 3/4x. If we divide -3/4 by -3/4, we'll get 1. So, divide both sides by -3/4

    -3/4x 21

    over = over

    -3/4 -3/4

    and you can do the rest!

    X = 6.

    OK

    - 7 + - 3 = -10, plus ten to 14 = 24. 24/4 = 6.
