Given that log₄(Y - 1) + log₄( $\frac{1}{2}$ x) = 1 and log₂(y + 1) + log₂x = 2, solve for x and y respectively

2, 3

3, 2

-2, -3

-3, -2

Correct answer is C

log₄(y - 1) + log₄( $\frac{1}{2}$ x) = 1

log₄(y - 1)( $\frac{1}{2}$ x) $\to$ (y - 1)( $\frac{1}{2}$ x) = 4 ........(1)

log₂(y + 1) + log₂x = 2

log₂(y + 1)x = 2 $\to$ (y + 1)x = 2₂ = 4.....(ii)

From equation (ii) x = $\frac{4}{y + 1}$ ........(iii)

put equation (iii) in (i) = y (y - 1)[ $\frac{1}{2}(\frac{4}{y - 1}$ )] = 4

= 2y - 2

= 4y + 4

2y = -6

y = -3

x = $\frac{4}{-3 + 1}$

= $\frac{4}{-2}$

X = 2

therefore x = -2, y = -3
