You undo one of the operations at a time, always with the aim of isolating the variable you want to solve for on one side.
The answer depends on the equation: there is no single method which can be used for all equations.
Not necessarily, but often it is simpler to convert fractions into decimals to solve the equation.
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.
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.
Tell me the equations first.
There are people who use this web site that can and will solve equations.
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect
The answer depends on the nature of the equations.
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.
You need as many equations as you have variables.
One can solve equations of motion by graph by taking readings of the point of interception.
