The value of x from the equation equations given where; (x,y) is a solution is; x = 3

According to the question given;

  • x2 + y2 = 153 and
  • y = -4x

By evaluating the value of y² and substituting into equation, x² + y² = 153 ; we have;

  • y² = 16x²

Therefore, we have;

  • x² + 16x² = 153

  • 17x² = 153

  • x² = 153/17

  • x² = 9

  • x = √9

x = 3.
