 Question 200349: The equation B=1+3n tells the number of beams required to build a frame of n sections. How many sections can be built with 79 beams?Answer by tutorcecilia(2152)   (Show Source): You can put this solution on YOUR website!B=1+3n 79=1+3n [substitute 79 for the B-variable] 79-1=1+3n [solve for the n-variable] 78=3n 78/3=3n/3 26 sections=n Checking: 79=1+3(26) 79=79
