Question

11. If 2x + 3y + 4 = 0 and v(x) = 6 then v (y) is
(a) 8/3
(b)
(c)
(d)
9
6
can anyone explain it's solution​

Answer 1

Answer:

2(6)=12................

hope it helps you

Answer 2

Step-by-step explanation:

v(x) = 6 [ given ]

But, v(x)= 2x + 3y +4= 0

v(6)= 2(6) + 3y + 4 = 0

= 12 + 3y + 4 = 0

= 16 + 3y = 0

= 3y = -16

= y = -16/3

Therefore, v(y) = -16/3

Checking-

v(x) = 6= x, v(y) = -16/3= y

Putting x & y in eq.

2x +3y + 4= 0

2(6) + 3(-16/3) + 4= 0

12 -16 +4 = 0

16-16 =0

0=0

LHS = RHS. CHECKED
