Ok, I almost feel embarrassed to ask as I should know this but here go.
7x + 3 = 5x - 4
I conclude x = positive 7 over 2
Wolfram says negative 7 over 2.
Can anyone just write down step by step to tell me where I'm going wrong.
Yes I know, school stuff. It's been a few years for me since
Before you ask, I'm trying to write software (for fun) which calculate variables and solve simple algebraic equations. It's strange that the equations stump me whilst the software don't
