What are two steps for eliminating the parameter for parametric equations?

For this explanation, let's assume you have a curve that is parametrically defined by:
x=4t
y=t2+et
An easy way to "eliminate" the parameter and therefore have a function defined by variables x and y is to solve for t using one of the parameterized variables:
x=4t, so t=x/4
This solution for t can be plugged into the other parametrized variable:
y=t2+et and t=x/4, so y=(x/4)2+ex/4
y=x2/16+ex/4
You now have a single-variable function equivalent to the parameterized curve. This method does not always work, but for most general calculus classes (especially Calc I), this is all that you will need to know.

How do you know that substitution gives the answer to a system of equations?
You put in the answers you got for your variables into one of the equations. If it gives you the correct answer then you solved it, if it's different then either it doesn't work or one of the steps wasn't completed correctly or at all.
Four steps to the elimination method?
There are four steps in an algebraic elimination problem. These steps are: to find a variable with equal or opposite coefficients, if equal then subtract the equations but if opposite then add, solve one variable equation left, and then substitute known variable into other equation and solve. hi

The steps that are taken are many,with errors they often are fraught.But don't feel dismay;keep pluggin' away!With practice is how you are taught.
Steps of how to solve a system of equations by substitution?
Step one is by expressing one of the equation into one term that is taking one unknown in the form of other. Step two is replacing the unknown into equation 2. Step 3 is replacing the found unknown into one of initial equations to find the other unknown.

What are the key steps you take to configure a server to prevent syn flood attacks?
Choose to add a new DWORD (32 bit) Value parameter and then enable the parameter by entering a data value.
What are the steps on solving equations?
The answer will depend very much on the nature of the equation. The steps required for a one-step equation are very different from the steps required for a partial differential equation. For some equations there are no straightforward analytical methods of solution: only numerical methods.

Can you skip steps or add step when solving rational equations?
Yes, but only if you know exactly what you are doing.
How do you solve two-step equations with fractions?
Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable.
