Question

2. Write four solutions for each of the following equations:
(i) 2x+y=7 (ii) Tx + y = 9 (iii) x=4y

Answer 1

Answer:

(i) 2x+y=7

when,

x=0 ; 2×0+y =7 ; y =7

x=1 ; 2×1 + y=7 ; y = 7-2=5

x=2 ; 2×2+y =7 ; y = 7-4= 3

x=3 ; 2×3+y =7 ; y = 7-6= 1

four solutions are (0,7),(1,5),(2,3),(3,1)
