You can solve the system of equations with three variables using the substitute method, or using matrix operations.
If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
Tell me the equations first.
Dimensional consistency is symbolic calculations that involves physical measurements. In physics equations, it is used in calculating the frequency.
You need as many equations as you have variables.
Ask you math professor
3*-7=29
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.

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.
To solve a system of equations, you need equations (number phrases with equal signs).
3(5x-2y)=18 5/2x-y=-1

To solve for 3 unknown variables you need 3 independent equations. You have only 1.
A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.
Its called Simultaneous Equations
