Answer 2

It seems like you have provided two equations involving the variable "x." Let's solve them one by one.

Equation 1: 2x - 3x - 77 = 0

Combine the x terms: -1x - 77 = 0

Add 77 to both sides: -1x = 77

Multiply by -1: x = -77

Equation 2: x^2 + 5x - 14 = 0

This is a quadratic equation. You can solve it using various methods, such as factoring, completing the square, or using the quadratic formula. I'll use the quadratic formula here:

The quadratic formula is given by: x = (-b ± √(b^2 - 4ac)) / 2a

In your equation, a = 1, b = 5, and c = -14: x = (-5 ± √(5^2 - 4 * 1 * -14)) / (2 * 1) x = (-5 ± √(25 + 56)) / 2 x = (-5 ± √81) / 2 x = (-5 ± 9) / 2

So the two possible solutions for Equation 2 are: x = (4/2) = 2 x = (-14/2) = -7

To summarize: Equation 1 has one solution: x = -77 Equation 2 has two solutions: x = 2 and x = -7
