The basic idea is that you need to carry out the same operations on both sides of an equation.
In a scale, assuming you want to keep it balanced, if you add 3 kg. on the left side, you also need to add 3 kg. on the right side.
With an equation, the situation is similar; except that you can not only add and take away (add and subtract), but also (with certain limitations and caveats which you should learn) multiply both sides by the same number or term, divide both sides, square, take square roots, take trigonometric and inverse trigonometric functions, etc.
What else can I help you with?
How do you solve these equations?
Tell me the equations first.
How do you solve multivariable equations?
You need as many equations as you have variables.
Why do you need to be able to solve equations?
If you don't learn to solve equations then guess and check is the only way to arrive at new information.
How do you solve 3 dimensional equations?
You can solve the system of equations with three variables using the substitute method, or using matrix operations.
What are simultaneous equation in maths?
Simultaneous equations are where you have multiple equations, often coupled with multiple variables. An example would be x+y=2, x-y=2. To solve for x and y, both equations would have to be used simultaneously.

Do you solve equations any differently if they contain fractions?
Not necessarily, but often it is simpler to convert fractions into decimals to solve the equation.
How do you solve these equations?
Tell me the equations first.
Does this web site solve equations?
There are people who use this web site that can and will solve equations.
How can you use a graph to solve systems of equations?
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect
How do you solve trigonometric equations?
The answer depends on the nature of the equations.
Can you solve for a variable in a equation?
Yes, that is often possible. It depends on the equation, of course - some equations have no solutions.
How do you solve equations with fraction?
You solve equations with fractions the same way you solve other equations. You perform various arithmetic operations on both sides of the equals sign until you get the result you want.
How do you solve multivariable equations?
You need as many equations as you have variables.
How we solve equations of motion by graph?
One can solve equations of motion by graph by taking readings of the point of interception.
What are the disadvantages to using equations?
Its harder to solve the equations with grande numbers
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. Solving Two Step Equations Involving Fractions This video explains how to solve two step equations involving fractions.
