How to Solve the Equation 15 = (x+2)/-3
Quick Answer
To solve the equation 15 = (x + 2)/-3, multiply both sides by -3 to isolate x. This gives x = -47 after performing the necessary arithmetic.
To solve the equation $$15 = \frac{x+2}{-3}$$, we need to isolate the variable x. Let's break it down step by step to ensure clarity.
First, the equation shows that $$15$$ is equal to $$\frac{x + 2}{-3}$$. To eliminate the fraction, we can multiply both sides by -3. This operation gives us:
$$15 \times -3 = x + 2$$
Calculating the left side, we get:
$$-45 = x + 2$$
Now, our goal is to isolate x. To do this, we need to get rid of the +2 on the right side. We can achieve this by subtracting 2 from both sides of the equation:
$$-45 - 2 = x$$
Performing the subtraction results in:
$$-47 = x$$
Thus, we find that:
$$x = -47$$
It's always a good practice to check our work. We can substitute $$x = -47$$ back into the original equation to verify:
$$15 = \frac{-47 + 2}{-3}$$
This simplifies to:
$$15 = \frac{-45}{-3}$$
And since $$\frac{-45}{-3} = 15$$, our solution is confirmed to be correct.
Understanding how to manipulate equations like this is crucial in mathematics. Equations are often used in real-world applications, from calculating expenses to understanding scientific concepts. Mastering these skills can greatly enhance your problem-solving abilities.
