Question

Which pairs make the equation x-9y=12 true

Answer 1

Answer:

The pairs (12,0)  , (3,-1)  and (0,-4/3)  make the equation x- 9 y = 12 TRUE.

Step-by-step explanation:

Here, the given equation is  x - 9 y = 12

Checking for each pairs individually:

a) For (12,0):

x - 9y  =   (12) - 9(0) = 12  

and 12  =  12 (Right Side).

Hence, (12,0) satisfies the equation.

b) For (0,12):

x - 9y  =  0 - 9(12) = -118  

and -118   ≠  12 (Right Side).

Hence,(0,12) DO NOT  satisfy the equation.

c) For (3,-1):

x - 9y  =   3 - 9((-1) ) =  3 + 9 = 12  

and 12  =  12 (Right Side).

Hence, (3,-1) satisfies the equation.

d) For (0,-4/3):

x - 9y  =   0 - 9((-4/3) ) =  0 + 12 = 12  

and 12  =  12 (Right Side).

Hence, (0,-4/3) satisfies the equation.

Hence, the pairs (12,0)  , (3,-1)  and (0,-4/3)  make the equation x- 9 y = 12 TRUE.
