Explanation:

x² + y² = 153 and y = -4x.

=> x² + (-4x)² = 153

=> x² + 16x² = 153

=> 17x² = 153

=> x² = 9.

Answer:

x² = 9

Explanation:

x² + y² = 153 ----------------------(I)

y = -4x ----------------------(II)

Plugin y = -4x in equation (I)

x² + (-4x)² = 153

x² + 16x² = 153

17x² = 153

x² = 153/17

x² = 9

x = √9

x = 3
