Chapter 3: Q18. (page 146)

Solve the system of equations by graphing.

-2x-6y=03x+11y=4

Short Answer

Expert verified

The solution of the equation is x=-6 and y=2

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 -2x-6y=0and3x+11y=4.

The points which satisfy the equation -2x-6y=0are (0,0) and(3,-1).

The points which satisfy the equation 3x+11y=4 are (5,-1) and(-6,2).

04

Step-4 –Plotting the graph


The two linear equations intersect at (-6,2) in the graph.
