Answer 1

Answer:

answer is

Step-by-step explanation:

21a=63

a=63/21

a=3

Answer 2

Given :-

Linear equation = (9ax + 12ay = 63 )

The value of x = 1

The value of y = 1

Solution :-

9ax + 12ay = 63

step 1 :- Put the values of ' x 'and ' y ' in the given equation

9a*1 + 12a* 1 = 63

9a + 12a = 63

21a = 63

step 2 :- Take 21 to RHS

(right hand side)

a = 63 /21

a = 3

The value of ' a ' is 3
