SOLUTION: Using transformation - solve each equation: 4/9x = 8 n/2.3 = 5.6 3/5n + 15 = 21 13

SOLUTION: Using transformation - solve each equation: 4/9x = 8 n/2.3 = 5.6 3/5n + 15 = 21 13 - 1/3n = 9 3/4n + 22 = 55

Question 62987: Using transformation - solve each equation:
4/9x = 8
n/2.3 = 5.6
3/5n + 15 = 21
13 - 1/3n = 9
3/4n + 22 = 55
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
(4/9)x = 8
Multiply both sides by 9/4 to get:
x=72/4=18
----------------
n/2.3 = 5.6
Multiply both sides by 2.3 to get:
n=12.88
--------------
(3/5)n + 15 = 21
(3/5)n=6
Multiply both sides by 5/3 to get:
n=10
--------------
13 - (1/3)n = 9
(1/3)n=3
n=9
------------
(3/4)n + 22 = 55
(3/4)n=33
n=44
