Question

Solve 5x +7 = 2x - 3

Answer 1

minus each side by 2x and seven so that you get....
\[3x=-10\]
so your \[x=\frac{-10}{3}\]

Answer 2

can i get your working please. I feel like youve just given me the answer ..

Answer 3

\[5x-2x+7-7=2x-2x-3-7\]

Answer 4

im sorry but im not following you

Answer 7

5x+7 = 2x-3


5x = 2x-3-7 ... Subtract 7 from both sides.


5x-2x = -3-7 ... Subtract 2x from both sides.


3x = -10 ... Combine like terms.


x = -10/3 ... Divide both sides by 3 to isolate x.


So the answer is x = -10/3

Answer 8

\[5x+7=2x-3\] now add (-7) in both sides
\[5x+7-7=2x-3-7\]
\[5x=2x-10\] now add -2x in both sides
\[5x-2x=2x-10-2x\]
\[3x=-10\] now divide both sides by 3
\[\frac{ 3x }{ 3 }= \frac{ -10 }{ 3 }\]
\[x= \frac {-10} {3}\]

Answer 9

so the answer cant be -3.3 ?

Answer 10

divide -10 in 3, please do it.

Answer 11

I'm sorry I didn't realise I was on facebook asking for help from retriceoles. I put it in a calculator and thats what I fluttering got. I havent been to school in almost two years I don't fluttering know much so excuse the flutter out of me for being just a little bit stupid.
There is no need for you to be a sarcastic flutter !

Answer 12

really ? I cant even swear.
omfg.

Answer 13

You're trying to combine like terms. It may help you to see it better if you put everything on one side of the equal sign.


\[5x+7=2x-3\]
Bring the 3 over by adding it to both sides. (-3+3 = 0)
\[5x+7+3=2x+0\]
Bring the 2x over by subtracting it from both sides (2x-2x=0)
\[5x+7+3-2x=0+0\]
Now group like terms together.
\[(5x-2x)+(7+3)=0\]
5x-2x=3x and 7+3=10 so we get:
\[(3x)+(10)=0\]
Remember, we are trying to get x by itself, so subtract the 10 from both sides.
\[3x=-10\]
And finally to get rid of the 3, we divide both sides by 3. (3/3 = 1)\[x=\frac{ -10 }{ 3}\]
