Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
Step-by-step explanation:
Given:
(y/y - 4) - (4/y + 4) = 32/y^2 - 16
Note y^2 - 16 = (y - 4 ) × (y + 4)
Multiplying the equation; both sides by y^2 - 16,
y (y + 4) - (4(y - 4)) = 32
y^2 + 4y - 4y + 16 = 32
y^2 = 32 - 16
Squaring both sides,
y = sqrt(16)
= 4
