I came back! I need help. I hope that my old brother/sister forum rats help me.
Question:
$$\textcolor[rgb]{1,0,0}{Solve\;for\;x:}\\\\ax=b\\\\x=?$$
Can someone please help me? Thank you.
This is a little equation that you are being asked to rearrange.
$$ax=b\\$$
You want the x out the front by itself. SO you have to get rid of the $$a$$
You can do this by dividing the LHS by $$a$$ but the equation must stay balanced.
Whatever you do to one side you must also do to the other side.
so this is what happens
$$\\ax=b\\\\
\dfrac{\not{a} x}{\not{a}}=\dfrac{b}{a}\\\\
x=\dfrac{b}{a}\\\\$$
