Question

X-y=1 x+y=3 in graphical method

Answer 1

Answer:

Point where the lines cross is:

(x,y)=(2,1)

Step-by-step explanation:

Consider:

x+y=3

Subtract x from both sides

The line crosses the x-axis at

y=0⇒0=−x+3⇒x=3

So we have

x

intercept→(x,y)=(3,0)

The line crosses the y-axis at

x=0⇒y=0+3

So we have y intercept(x,y)=(0,3)
