Question

if a point A (-4, a) is located on the line whose equation is 3x + 2y -4 = 0 Then the value a is? ​

Answer 1

Answer:

a = 8

Step-by-step explanation:

3x + 2y -4 = 0

3(-4) + 2y -4 = 0

-12 + 2y-4 = 0

-16 + 2y = 0

2y = 16

y = 8

Answer 2

Answer:

Here , x= -4 y= a

3x+2y-4=0

3(-4)+2a-4=0

-12+2a-4=0

2a-16=0

2a=16

a= 16/2

a=8
