Question

x-y=3 ; 3x+2y=19 by graphical method

Answer 1

Answer:

Step-by-step explanation:

x-y=3. -y=3-x(put the value)

So x is independent and y is dependent

Lets take x. 0. 1. -1

y. -3. -2. -4

Another 3x +2y =19

So 2y=19-3x. y=19-3x/2

X. 1. -1. 3

Y. 8. 11. 5

Done now put these value in graph and join the points

Hope it helpark as brainliest

Answer 2

Answer:

(5, 2)

Step-by-step explanation:

y = mx + b , where slope m = $\frac{rise}{run}$ , "b" is y-intercept.

~~~~~~~~~~

x - y = 3 ===> y = x - 3

m = 1 , b = (- 3) , ( 3, 0)

3x + 2y = 19 ===> y = - $\frac{3}{2}$ x + $\frac{19}{2}$

m = - $\frac{3}{2}$ , b = $\frac{19}{2}$ , ( $\frac{19}{3}$ , 0)

Solution of system of equations is (5, 2)
