Question

Find the solution of the following pair of linear equation graphically 4x+y=-5 and x+2y=4

Answer 1

Answer:

Step-by-step explanation:

X= -2 y=3

Answer 2

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

We have given two pair of linear equations and we have to find the value of x and y through graph.

For that firstly convert the Equation either in the form of x or y and then plot points into and obtained the coordinate . Put the coordinate into graph of both the Equation and we obtained a interesting point with the help of coordinate of both the Equation which will be our final solution.

➙ 4x+y= -5

➙x+2y=4

Taking first Equation

y= -5-4x-------(1)

At x= 0

➙y= -5

At x= 1

➙y= -9

Plot the points (0,-5)& (1,-9) into the graph

---------------------------------------------------------

Taking second Equation

x+2y=4

➙x= 4+2y--------(2)

At y =0

➙x= 4

At y=1

➙x= 6

plot the points (4,0)& (6,1) into the graph

After plotting the points we obtained a straight line graph which intersect at the points (-0.667,-2.333).
