Do i plus or minus simultaneous equations?
When solving simultaneous equations, you can use either addition or subtraction, depending on the equations. If the coefficients of one variable are the same (or negatives of each other), you can add or subtract the equations to eliminate that variable. This method simplifies the system, allowing you to solve for the remaining variable. The choice to add or subtract should be based on which method will simplify your calculations most effectively.
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.

When do two negatives make a positive?
Two negatives make a positive in multiplication and division
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.
How do you solve two-step equations with fractions on one side?

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.

What do two negatives equal two?
When combining (adding) two negatives you get a negative. When multiplying two negatives you will get a positive.
How do you solve rational equations?
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.
