Question

solve this graphically 2x+y=10 and x+y=7​

Answer 1

here is ur answer I think this may help u.....

Answer 2

The solution of equations are $\bf x = 3$ and $\bf y = 4$

Given:

• $2x + y = 10...eq1$ and $x + y = 7...eq2$

To find:

• Solve the equations Graphically.

Solution:

Step 1:

Find atleast two points in eq1.

$y = 10 - 2x$

put x= 0

$y = 10$

One point is (0,10)

Put x=4

$y = 10 - 8$

or

$y = 2$

Another point is (4,2)

One more point (5,0)

Draw the straight line while joining these points.

Step 2:

Find atleast two points in eq2.

$y = 7 - x$

put x= 0

$y = 7$

One point is (0,7)

Put y=0

$x=7$

Another point is (7,0)

Draw the straight line while joining these points.

*Graph of lines is attached.

Step 3:

Intersection of lines is the solution of eqs.

Thus,

$\bf x = 3$ and $\bf y = 4$ is the solution.
