Question

solve 2x+y-5=0 ; 3x-2y-4=0 graphically​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

$\bf x = 2 \: and \: y = 1$ is the solution of equations.

Step-by-step explanation:

Given:

• Two linear equations.
• $2x + y - 5 = 0$ and $3x - 2y - 4 = 0$

To find:

• Solve the equation graphically.

Solution:

Method to be used:

1. Draw both lines by finding at least two-2 points of each line.
2. Write the point where both lines intersect, that is the solution of equations.

Step 1:

Find points on both lines.

For line:$\bf 2x + y -5 = 0$

$\begin{tabular}{|c|c|c|}\cline{1-2}x&y\\\cline{1-2}0&5\\\cline{1-2}2&1\\\cline{1-2}\end{tabular}$

For line:$\bf 3x - 2y - 4 = 0$

$\begin{tabular}{|c|c|c|}\cline{1-2}x&y\\\cline{1-2}0&-2\\\cline{1-2}4&4\\\cline{1-2}\end{tabular}$

Plot these points and draw both lines.

Step 2:

Find the solution of equations.

*See attachment.

Both the lines intersect at a point (2,1).

So,

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

Thus,

$\bf x = 2 \: and \: y = 1$is the solution of equations.
