13. 71.5=5.5u divide each side by 5.5 to solve for u
71.5/5.5=13 so u=13

14. 5/6x=5/14 to solve for x you divide both sides by 5/6.  But to divide fractions you multiply the reciprical.  So:
x=5/14*6/5=30/70 or 3/7

15. 44=t/11 multiply both sides by 11 to solve for t
484=t

16. 8.3=b/14 multiply both sides by 14 to solve for b
116.2=b

17. x/3= 15 multiply both sides by 3 to solve for x
x=45

18. 7.8x=23.4 divide both sides by 7.8 to solve for x
x=3

Solving system by substitution x=3y+11, 2x-3y=16
grin007 [14]
Input 3y+11 for x

2(3y+11)-3y=16
6y+22-3y=16
3y= -6
Divide by 3 to isolate y
y=-2

Now for x....

x=3(-2)+11
=-6+11
=5
x=5
