Chapter 11: Q. 26 (page 714)

Solve each system of equations. If the system has no solution, say that it is inconsistent.
$\{\begin{matrix} x - y = 5 \\ - 3 x + 3 y = 2 \end{matrix}$

Short Answer

Expert verified

The given system of equations is inconsistent.

Step by step solution

Step 1. Given information.

The given equations are:

$\begin{array}{rcl} x - y & = & 5 \\ - 3 x + 3 y & = & 2 \end{array}$

Step 2. Determine one variable in terms of another variable.

The first equation can be written as:

$\begin{array}{rcl} x - y & = & 5 \\ x & = & 5 + y \end{array}$

Step 3. Determine the value of one variable.

Substitute the above value in the second equation.

$\begin{array}{rcl} - 3 (5 + y) + 3 y & = & 2 \\ - 15 - 3 y + 3 y & = & 2 \\ - 15 & = & 2 \end{array}$

This statement is false, it means the system has no solution. So, the given system of equations is inconsistent.
