To determine To calculate: The solution by the use of substitution method of the system of equations, x + 3 y = − 2 y = − 1 3 x − 2 3 . Explanation Given Information: The provided system of equations is, x + 3 y = − 2 y = − 1 3 x − 2 3 Formula used: Steps for substitution method is mentioned below, Step 1: Identify a variable with numerical coefficient 1 in the provided system of equations and solve the equation for the corresponding variable. If there is no variable with coefficient 1 , solve for any variable in either equation. Step 2: Substitute the value of the variable obtained in the step 1 into the other equation and simplify the equation to obtain an expression containing only one variable. Step 3: Find the value of the variable by solving the expression obtained in step 2 . Step 4: Substitute the value of the variable obtained in the expression obtained in step 1 . Step 5: Now, write the solution as an ordered pair. Step 6: Verify your solution, by substituting the value in all the equations. Calculation: Consider the provided system of equations, x + 3 y = − 2 y = − 1 3 x − 2 3 Observe that in the equation y = − 1 3 x − 2 3 the coefficient of y is 1

Family of Curves

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

XZ Plane

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Euclidean Geometry

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

Lines and Angles

In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.

Solve the linear system of equations attached using Gaussian elimination (not Gauss-Jordan) and back subsitution. Remember that: A matrix is in row echelon form if Any row that consists only of zeros is at the bottom of the matrix. The first non-zero entry in each other row is 1. This entry is called aleading 1. The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.
