Question

By substitution method solve : x/3 + y/4 =6 , x/6 + y/2 = 6​

Answer 1

Step-by-step explanation:

x + y = 6....1 ; x + y. =6....2

3. 4. 6. 2

from 1&2

x + y = x + y.

3. 4. 6. 2

x - x. = y. - y

3. 6. 2. 4

6x-3x = 4y-2y

18. 8

3x = 2y

18. 8

x = y

6. 4

x = 6y

4

x =3y

2

from eq 1

3y/2 + y. = 6

3. 4

3y + y = 6

6. 4

y + y = 6

2. 4

2y+y. = 6

4

3y = 24

y=8

but,

x= 3y

2

x= 3*8

2

x=12

(X,Y) =(12,8)
