Question

let us draw the graph of tye simultaneous linear equations and determine the co-ordinates of rhe point of intersection
(iii) x+y=12 and x-y=2​

Answer 1

1. i. Plot the above ordered pairs on the same co-ordinate plane
2. Draw graphs of the equations.
3. Note the co-ordinates of the point of intersection of the two graphs. Write solution of these equations
4. x - y = 1 5x-3=1
5. The two lines intersect at point (-1, -2). ∴ (x , y) = (-1, -2) is the solution of the given simultaneous equations.
