How would I solve this?
Is there a way to solve for x in the following equation without simplifying at all?

14.78 + 5X + 6(3.42) + 2.23(X-4) = 0

This should work in CAS. Please note the lower case 'x'

solve((14.78+5*x+20.52+2.23*(x-4)) = 0,x)

Result {−3.64868603043}

Try this in HOME:

solve("14.78 + 5*X + 6*(3.42) + 2.23*(X-4) = 0,X");

Notice: Implicit multiplications are expanded using the * symbol. Since the CAS (lower case) solve command is used, quotation marks are required in HOME.
