Question

Write three solutions for the following equations: (i) 2x+y=7 (ii) 2x=6y

Answer 1

Answer:

(I) x=1,y=5

x=2,y=3

x=3,y=1

(ii) x=6,y=2

x=9,y=3

x=12,y=4

Answer 2

Answer:

1) 2x+y=7

now arrange eq 2

3) 2x-6y=0

subtract eq3 by eq1

Step-by-step explanation:

7y=7

y=1 eq4

put this in eq2

then

x=3

(x,y)=(3,1)
