Question

2x+y=5 and x+y=4 solve graphically

Answer 1

Answer:

So start from Equation

2x+y=5 And

x+y=4

we solve by elimination method

2x+y=5 ( Equation 1 )

x+y=4 ( Equation 2) Now Eliminate it by changing signs

- - - (Change the sign from '+' to '-')

x = 1

Putting the value of x in Equation 2

x + y =4

1 + y =4

y = 4 - 1

y = 3

So x=1 and

y=3
