Use properties of equality and numbers to solve each equation for x.
A. 7+3x = 5x + 13
how am i suppose to solve i am kind of confused?!?!
I asked a question earlier:
Identify and discuss 4 key actions taken by the U.S. Government between 1790 to 1820 that established long term policy in the U.S. Please help me answer this, thank you so much.
and I got this response:Please note that we don't do students' assignments for them. Be sure to go back into your textbook or use a good search engine.
Funny how I got this response, when clearly you give away answers. Can we say hypocrites?
7+3x = 5x + 13
7 - 13 = 5x -3x
-6 = 2x
-3 = x
Thank you Ms.Sue!!
You're welcome EmilyMay.
Jack -- I'm sorry you don't see the difference between working one math problem and writing a complex essay involving several paragraphs.
Hmmm well I certainly didn't want them to write a complex essay for me, just some a little help and some ideas. It's whatever though.
To solve the equation 7 + 3x = 5x + 13 for x, you will need to use the properties of equality and numbers.
Step 1: Simplify both sides of the equation by combining like terms.
On the left side, you have 7 + 3x. There are no like terms to combine, so it remains as 7 + 3x.
On the right side, you have 5x + 13. Again, there are no like terms to combine, so it also remains as 5x + 13.
Step 2: Move the x terms to one side of the equation and the constant terms to the other side.
Start by subtracting 3x from both sides of the equation to move the x term to the right side. This gives you:
7 + 3x - 3x = 5x - 3x + 13
Simplifying further, you have:
7 = 2x + 13
Next, subtract 13 from both sides of the equation to move the constant term to the left side:
7 - 13 = 2x + 13 - 13
This simplifies to:
-6 = 2x
Step 3: Solve for x.
To isolate x, divide both sides of the equation by 2:
(-6)/2 = (2x)/2
This simplifies to:
-3 = x
Therefore, the solution to the equation is x = -3.
