Tell me the equations first.

You can solve the system of equations with three variables using the substitute method, or using matrix operations.

If you don't learn to solve equations then guess and check is the only way to arrive at new information.

You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.

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.

One can solve equations of motion by graph by taking readings of the point of interception.

Its harder to solve the equations with grande numbers

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.

The answer depends on whether they are linear, non-linear, differential or other types of equations.

To solve a system of equations, you need equations (number phrases with equal signs).
