Question

hi guys x+y/2 = 1
x/3 +17y/6 =3
plzz solve it by substitution method​

Answer 1

Answer:

1. x = 1 - y/2 .....(1)
2. therefore x = (2-y)/2
3. now putting the value of x in eq 2
4. (2-y)/3*2 + 17y/6 = 3
5. (2-y)/6 + 17y/6 =3
6. (2 + 16y)/6 = 3 ...same denominators
7. 2 + 16y = 18
8. 16y = 16
9. y = 1
10. putting y = 1 in (1)
11. x = 1/2
12. therefore x =1/2 y = 1
