tricky...it has alot to do with trial and error!
step 1: Get the question e.g: 1 x 4y = 3 + 2y...what is y?
step 2: Rearange the words (group the words ending with x to the normal ones)
e.g: 1 x 2 = 4y -2y
step 3; THINK LOGIC! E.g: 4 times y takeaway 2 times y is y doubled. y x 2 = 2
y x 1=1 so y is 1!

How does a method for solving equations with fractions to decimal point that she's in conference compare with the method for solving equations with integer coefficients and constants?
The method is exactly the same.
Where did complex and imaginary numbers come from?
The 16th century Italian mathematician, Gerolamo Cardano was the first to use imaginary and complex numbers in his work on cubic equations.
What are the values called at which the equation equals zero?
They are called the solutions or roots of the equations.
Is there a difference between rational expressions and rational equations?
Yes. An equation has an "=" sign.
Is the number '0' actually a number?
yes. numbers can be seen as solutions to equations and zero can be.
Do you have to use the same variables for all equations when creating a system of equations?
The idea is to work with the same variables, but it is possible that some of the variables are missing in some of the equations.
What is are equations in a worksheet?
Spreadsheet equations help you get work done more efficiently. If you enter a new set of data, the equations will automatically adjust to the data you just put in.
How can you determine if the given ordered pair is a solution to the system of equations?
Plug your ordered pair into both of your equations to see if you get they work.
What term is defined as mathmatical equations based on rules of physics?
work = force x distance time = distance : time power = work : time force = ?
What can you do on a spread sheet?
Difficult mathematical equations as the software can work it out for you
What do you call the graphs that intersect at exactly one point which gives solution of the system?
They are straight line graphs that work out the solutions of 2 equations or simultaneous equations
What did John Crank discover?
He did poineering work in differential equations. See link.
Are Kinematics equations only used by physicists and people who work at NASA.?
False.
What 19th century french mathematician did very innvoative work with equations?
Hermite
What are the task of a chemistry?
To see what happens when chemicals are mixed together and also work out equations
How do you work a simultaneous equation?
You cannot work a simultaneous equation. You require a system of equations. How you solve them depends on their nature: two or more linear equations are relatively easy to solve by eliminating variables - one at a time and then substituting these values in the earlier equations. For systems of equations containing non-linear equations it is simpler to substitute for variable expression for one of the variables at the start and working towards the other variable(s).
What are the different Types of mathematical equations?
Algebraic equations, trigenometric equations, linear equations, geometric equations, partial differential equations, differential equations, integrals to name a few.
