Final answer:
The correct answer is option B: x = 5,we need to isolate the variable x, which is found by simple algebraic manipulation.
Step-by-step explanation:
To solve the equation 5 + 9x = 50, we need to isolate the variable x. First, we subtract 5 from both sides of the equation, which gives us 9x = 45. Next, we divide both sides by 9 to find the value of x, resulting in x = 5. This straightforward algebraic manipulation demonstrates that the provided linear equation is simple to solve and does not require the quadratic formula, which is used for quadratic equations, not linear ones like this.
This gives us 9x = 45. Next, divide both sides of the equation by 9 to solve for x. This gives us x = 5. Finally, we can check our solution by substituting x = 5 back into the original equation, which gives us 5 + 9(5) = 50. This simplifies to 5 + 45 = 50, which is indeed true.
