a = The cost of the pizza.
b = The cost of the pizza and sales tax.
f(a) = The cost of the pizza.

Answer: 1.12099824328 or estimated is 1
Start off by combining like terms on the LHS (the terms with x in them).
So we get

Replacing this result with what we had before on the LHS, we get

⇒Solve for x (divide both sides

)
⇒Don't forget about reciprocity rules when dividing. This is the same as multiplying both sides by

⇒

⇒

***This is a proper fraction
