Question

Chapter 5.4, Problem 21E

To determine

To find: The number of solutions of the system of linear equations −18x+6y=24 and 3x−y=−2 by the use of only the slopes and y-intercepts of the linear equations.

Expert Solution & Answer

Answer to Problem 21E

The system of linear equations −18x+6y=24 and 3x−y=−2 has no solution.

Explanation of Solution

Given information:

The system of linear equations is as follows:

−18x+6y=24 and 3x−y=−2

Concept used:

The slope intercept formis y=mx+b .

Here, m is the slope of the equation and b is the y -intercept of the equation.

The condition of infinitely many solution: If the two linear equations has same slope and also has same y-intercept then the two equations has infinite many solutions.

The condition of no solution: If the two linear equations has same slope but has no same y -intercept then the two equations has no solution.

The condition of one solution: If the two linear equations has different slope but has either the same y -intercept or different y -intercept then the two equations has one solution.

Calculation:

The given system of linear equations is as follows:

−18x+6y=24 .................. (1)

3x−y=−2 .................. (2)

Transform equation (1) in the form of slope intercept form.

−18x+6y=246y=24+18xy=24+18x6y=3x+4

Compare the obtained equation withgeneral slope intercepts form to obtain the slope and y -intercept of the equation (1).

m=3,y=4

Transform equation (2) in the form of slope intercept form.

3x−y=−2−y=−2−3xy=2+3xy=3x+2

Compare the obtained equation to slope intercepts form to obtain the slope and y-intercept of the equation (2).

m=3,y=2

Therefore, the slope of both equation (1) and equation (2) is same that is 3 but their y -intercepts is different that are 4 and 2 .

As per the concept, the equation (1) and equation (2) represents parallel lines on the graph and parallel lines never intersect each other.

Therefore, it can be concluded that the given system of linear equation has no solution.

Conclusion:

Thus, the system of linear equations −18x+6y=24 and 3x−y=−2 has no solution.
