Please note the lower case 'x' solve((14.78+5*x+20.52+2.23*(x-4)) = 0,x) Result {−3.64868603043} Cheers, Terje RE: How would I solve this? - DrD - 06-26-2016 07:59 PM 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. -Dale- RE: How would I solve this? - MattH - 06-27-2016 09:34 AM Great. Thanks to the both of you!
