Chapter 4: Q 203 (page 443)

Write the system of equations that that corresponds to the augmented matrix.

2-20-102-1230-1-2

Short Answer

Expert verified

2x-2y=02y-z=23x-z=-2

Step by step solution

01

Step 1. Given Information

A matrix is given as-

2-20-102-1230-1-2

02

Step 2. Calculating equations

Each row of the matrix represents an equation in three variables as x,y&z.

The matrix given is a 3脳4matrix.

Assume first column as coefficients of variable x, similarly second for yand third for z.

Therefore the required system of equations is-

2x-2y=02y-z=23x-z=-2

To decide whether it would be more convenient to solve the system of equations by substitution or elimination.

(a)y=4x+95x-2y=-21(b)9x-4y=243x+5y=-14

Solve the system by graphing:

y=-3x-66x+2y=-12

Without graphing, determine the number of solutions and then classify the system of equations.

5x+3y=42x-3y=5

Without graphing, determine the number of solutions and then classify the system of equations.

y=32x+12x-3y=7
