Question

Solve the following simultaneous equations graphically.

(1) x + y = 6 ; x - y = 4
​

Answer 1

x + y = 6

x - y = 4

---------------

by elimination method,

2x = 2

x = 2/2

x = 1

sub/: x = 1 in eqn

1 + y = 6

y = 6-1

y = 5

Answer 2

Step-by-step explanation:

X+y= 6

x -y=4

by elimination method,

2x 2

x = 2/2

x=1

sub/: x =1 in eqn

1+y=6

y6-1

y= 5
