How did you get to that answer?
I want to learn it, not just get answers haha
Follow the "golden rule" of algebra. Thou shalt do to one side of the equal sign as thou do to the other side.
In this case subtract x. You now have -1.5x + 2 = 7 Do you see why?
Yeah
Continuing, now subtract 2. You now have: -1.5x= 5 Again did you follow?
\[\Huge{\frac{1}{2}x+2=x+7}\]\[\Huge{\frac{x+2}{2}=\frac{x+7}{1}}\]By cross multiplication we have,\[\Huge{(x+2)=2(x+7)}\]Solve this for \(x\).
Yes
I think you are on track. We only now have to do is divide by -1.5 We now have x = -(5/1.5) Using calculator divide 5 by 1.5 and prefix the minus sign.

This gives an odd ball answer of 3.33333
After getting the value u just need t put minus before the digit :)
or I should say -3.333 but it needs to be checked out by substituting it in the original problem to be sure we have not erred. To err is human.
The original equation was: - 1/2 x + 2 = x + 7 lets call the answer -3 1/3 and substitute it in the original. we would have: -1/2 (-3 1/3) +2 = -3 1/3 + 7 (-1/2)(-10/3) + 2= 3 2/3 10/6 + 2 = 3 2/3 5/3 + 2 = 3 2/3 3 2/3 = 3 2/3 verified!
Did following that help, just remember the golden rule and you won't unbalance the equation. When you unbalance the equation it will result in an incorrect answer.
This is my input for this morning. Good luck with your studies.
Thank you so much, and thank you for serving in the Army(:
No problem and as I saId good luck with your studies. Don't be discouraged when faced with a difficult problem, accept the challenge and try and solve.
Oh yes, your flag does not offend me.
