Question

If x=1,y=1 is a solution of equation 9ax+12ay=63,then the value of a is *

Answer 1

Answer:

a=3 is the answer

Step-by-step explanation:

we have given that

x=1

y=1

so we can say

x=y=1

so in this question, when we imply this formula's that is x=y=1

we get

9ax+12ay=63

9a+12a=63                                            Since x=y=1, so this value does affect                          

21a=63                                                          anyway so we can get avoid it

a=63/21

a=3

hope it helped

so pls mark me a brainlist
