Ok .. I need to solve for F and A in this problem below. The question is how do you program that

Equation 1: 190 = (F/2) + A

Equation 2: 169 = ((F/2) ¨C A) * -1

BTW I worked it out with pen and paper (Substitution Method) the answers are:

F=21

A=179.5

Thx again guys ... been a really big help!
