Chapter 3: Q19. (page 146)

Solve the system of equations by graphing.
$\begin{matrix} 3 x - 5 y = - 13 \\ 4 x + 2 y = 0 \end{matrix}$

Short Answer

Expert verified

The solution of the equations is $x = - 1$ and $y = 2$ .

Step by step solution

Step-1 – Concept of solution of linear equations

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

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.

Step-3 – Evaluation of points

The given linear equations are $3 x - 5 y = - 13$ and $4 x + 2 y = 0$ .

The point which satisfies the linear equations $3 x - 5 y = - 13$ are $(- 1, 2)$ and $(- 6, - 1)$ .

The point which satisfies the linear equations $4 x + 2 y = 0$ are $(0, 0)$ and $(- 1, 2)$ .

Step-4 –Plotting the graph

The two linear equations intersect at $(- 1, 2)$ in the graph.
