You have to multiply both sides (the entire thing) by -1. It's complicated, so save it for when you have a trinomial or less on both sides.

How do you solve two-step equations with fractions on one side?
Assuming you want to get rid of the fractions, you can multiply both sides of the equations by the greatest common factor of the fractions. Then you can solve the equation normally.
How do you solve simultaneous equations that include negatives?
You solve simultaneous equations involving negatives the same way you solve simultaneous equations not involving negatives. You subtract an appropriately scaled version of one from the other in order to cancel the terms of one variable, solving for the other variable. Remember that multiplying by -1 will reverse the signs, so that can be a trick to being able to visualize the subtraction. An example... 3x - 2y = 7 4x + 4y = -3 Multiply the first equation by -2 and solve for x... -6x + 4y = -14 4x + 4y = -3 -------------------- -10x = -11 x = 1.1 Backsubstitute and solve for y 3x - 2y = 7 3.3 - 2y = 7 -2y = 3.7 y = -1.85 Its just a matter of keeping the signs straight and remembering that subtracting a minus means to add. You can also add the equations instead of subtracting, if it seems that would also cancel a term.

How to do two step equations fractions?
I am not sure what you mean with "two step"; also, the details depend on solving equations depend on the specific equation. However, one thing you can often do to simplify equations with fractions is multiply left and right by the common denominator of all fractions - that way, you get rid of the fractions. Here is an example: (1/2)x + 3 = (2/3)x + 5 If you multiply both sides by 6, you'll get rid of the fractions (only whole numbers remain); this makes the equation easier to solve: 3x + 18 = 4x + 30
What is a method for solving a system of linear equations in which you multiply one or both equations by a number to get rid of a variable term?
It is called solving by elimination.

Why does the number of negative factors affect the signs of the product in math equations?
Multiplying or dividing a positive and negative gives a negative result. Multiplying or dividing two negatives gives a positive result.
