Question

Guys please give explanation to this question's answer .. If it's appropriate I will mark it as the brainliest​

Answer 1

Answer:

Step-by-step explanation:

3^(X - Y) = 27 AND 3^(X+Y) = 243

ON SIMPLYFING , WE GET :

3^(X - Y) = 3^3  AND 3^(X + Y) = 3^5

AS BASE IN BOTH SIDES OF BOTH EQUATIONS ARE SAME , WE CAN WRITE:

X - Y = 3   AND X + Y = 5   ( ON ELIMINATING THE BASES)

WE CAN ALSO WRITE X - Y = 3 AS X = 3 + Y

THEREFORE, ON PUTTING THE VALUE OF X , WE GET ;

X + Y = 5

(3 + Y) + Y = 5

3 + 2Y = 5

== 2Y = 2

== Y = 1

ON PUTTING THE VALUE OF Y , WE GET

X - 1 = 3

X = 4

THE VALUE OF X IS 4 AND Y IS 1
