x=-c/(a-b)

Explanation:

"Collect terms in x on the left side "

"subtract "bx" from both sides"

ax-bx=-c

"take out a "color(blue)"common factor "x

x(a-b)=-c

"divide both sides by "a-b

x=-c/(a-b)

x=-c/(a-b)

Explanation:

If we want to solve for x, we can first get all of our x terms on one side. This can easily be done by subtracting bx from both sides.

We now have

ax-bx=-c

Since both terms on the left have an x in common, we can factor that out to get

x(a-b)=-c

Lastly, we can divide both sides by a-b to get

x=-c/(a-b)

Hope this helps!
