Chapter 3: Q14. (page 145)

Solve the system of equations by graphing.

20y+13x=100.65x+y=0.5

Short Answer

Expert verified

The system of equation has infinite solutions.

Step by step solution

01

Step-1 – Concept of solution of linear equations

The solution of the equation is the point where the two line intersect the graph.

02

Step-2 – Concept of plotting the graph of linear equation

The linear equation can be plotted in the graph by taking at least two points which satisfies the linear equations.

03

Step-3 – Evaluation of points

The given linear equations are 20y+13x=10and0.65x+y=0.5.

The point which satisfies the equation20y+13x=10are(0,0.5)and(1013,0).

The point which satisfies the equation 0.65x+y=0.5are (0,0.5)and(1013,0).

04

Step-4 –Plotting the graph

The two equations represent same straight line and so has infinite solutions.
