Solve: 5x+9=5+3xa)-2b)-1c)2d)none of theseCorrect answer is option 'A'...
To solve the given equation, we need to isolate the variable x.
Given equation: 5x + 9 = 5(3x)
Step 1: Distribute the 5 on the right side of the equation:
5x + 9 = 15x
Step 2: Move all the terms containing x to one side of the equation by subtracting 5x from both sides:
9 = 15x - 5x
Simplifying the equation gives:
9 = 10x
Step 3: To solve for x, divide both sides of the equation by 10:
9/10 = x
Simplifying the fraction gives:
x = 0.9
Therefore, the correct answer is option A, -2.
Explanation:
The given equation is 5x + 9 = 5(3x). We can solve this equation step by step to find the value of x. By distributing the 5 on the right side, we get 5x + 9 = 15x. Next, we need to move all the terms containing x to one side of the equation. By subtracting 5x from both sides, we get 9 = 15x - 5x, which simplifies to 9 = 10x. To solve for x, we divide both sides of the equation by 10, giving us 9/10 = x. Simplifying the fraction, we find that x = 0.9. However, this does not match any of the given answer choices. Therefore, the correct answer is none of these (d), not option A (-2).
