Question

solve for x and include restrictions.  X can not be part o restriction

anonymous · Answer

so when we solve for x we cant use the restrictions that are given? but then how do we give the restrictions..

anonymous · Answer

x=(d-bx)/2c and c not equal to 0

anonymous · Answer

oops sorry

anonymous · Answer

its d-bc not d-bx

anonymous · Answer

i agree with c cannot equal 0, but what about the restriction of 3x cannot equal -b? since we cant use this, what do we do?

anonymous · Answer

@physo

anonymous · Answer

what do u mean?

anonymous · Answer

3x cannot equal -b is given as part of the problem.  But it says we cant use this restriction because x is part of the restriction.. how can we avoid this?

anonymous · Answer

oh i didnt read that part. so another condition would be c not equal 3d/b

anonymous · Answer

how?

anonymous · Answer

well, if you substitute x in 3x not equal -b, youll get it

anonymous · Answer

you can also write it as bc/d not equal 3
