I have the qustion 2x+5=-7, and I've figured out that I have to subtract 5 from both sides. However, now I'm left with a plus sign that I don't know what to do with? What do I do next? HELP! THIS IS COMONG FROM A BALLERINA, AND I HATE MATH!
Please don't switch screen names.
2x+5=-7
This equation means that 2 times some number plus 5 = -7
2x + 5 - 5 = - 7 + (-5)
2x = -12
x = ?
x=-12/2
x=-6
yeah well im a 16 year old student and i hate math. what makes u so special? u prance around a stage in ugly tutus and tights.
Hi there! Don't worry, I'm here to help you with your math problem. After subtracting 5 from both sides of the equation 2x+5=-7, you're correct that you'll be left with a plus sign.
To solve for x, you need to isolate the variable on one side of the equation. Since 5 is being added to the term 2x, you can eliminate the plus sign by subtracting 5 from both sides again.
Let's perform the next step together:
2x + 5 - 5 = -7 - 5
On the left side, 5 - 5 is 0, and on the right side, -7 - 5 is -12. Simplifying further, we have:
2x = -12
Now, you are left with 2x = -12. To solve for x, you need to divide both sides of the equation by 2:
(2x)/2 = (-12)/2
Dividing both sides by 2, we get:
x = -6
So, the solution to the equation 2x+5=-7 is x = -6.
Remember, when solving equations, the goal is to isolate the variable to find its value. Feel free to ask if you have any more questions, and I'll be here to assist you!
