Question

x+y+6,x-y=4 solve simultaneous equations graphically

Answer 1

let x+y=6 be eq 1 and x-y=4 be eq 2 Add eq 1and2 and x=5 and y=1

Answer 2

Answer:

∴ y = 6 – x ∴ y = x – 4

The two lines intersect at point (5, 1).

∴ x = 5 and y = 1 is the solution of the simultaneous equations x + y = 6 and x – y = 4.
