Question

x+y=5,2x-y=4 solve graphically​

Answer 1

Answer:

x+y=5,2x-y=4

2(3)-(2)

=6-2

=4

there for y=4

Answer 2

The equations can be solved graphically and the solution was found as (3,2).

Solving equations

Given equations are,

$x+y=5\\2x-y=4$

We can use different values of x and substitute in the equation and find the y - values and plugin those (x,y) values in the graphs and we can find the solution using the graph.

We can rewrite the equation for y as,

$y = 5 - x \\y = 2x - 4$

and we can find the values of y by plugin different values of x.

Thus the intersection of the lines can be termed as solution (3,2).

So the solution was found as (3,2)
