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.
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.

Two negatives make a positive in multiplication and division
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
It is called solving by elimination.
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.
Multiplying or dividing a positive and negative gives a negative result. Multiplying or dividing two negatives gives a positive result.

When combining (adding) two negatives you get a negative. When multiplying two negatives you will get a positive.

Double negatives are illogical.
McLaren's Negatives was created in 2006.
The details really depend on the equation. It often helps to multiply all parts of the equation by a common denominator, to get rid of the fractions.
The duration of McLaren's Negatives is 600.0 seconds.
