Question

5x-y=17 and2x-2y=2by graphical
method

Answer 1

Step-by-step explanation:

By equation we can draw the graph

but here by equational soln

multiply 5x-y=17 by 2 then it will become

10x-2y=34

now minus the eqn 2x-2y=2 :

10x-2y=34

- 2x-2y=2

_________

8x=32

x=4

2(4) -2(y) =2

2y = 8-2=6

y=3
