Answer:
x = 43
Step-by-step explanation:
2x + 16 = 3(x - 9)
2x + 16 = 3x - 27
2x - 16 = 3x -27 (-16)
2x = 3x -43
2x (-3x) = -43
-1x or -x
-x = -43
-43/ -x = 43

Example to help you out!
May rides her bike the same distance that leah walks. may rides her bike 10 km/h faster than leah walks. if it takes may 1 h and leah 3 h to travel that distance, how fast does each travel?
----------------------------------------
May DATA:
time = 1 hr. ; rate = x+10 mph ; distance = rt = (x+10)*1 mi
--------------------
Leah DATA:
time = 3 hr. ; rate = x mph ; distance = rt = 3x mi
-----------------------
Equation:
distance = distance
x+10 = 3x
2x = 10
x = 5 mph (Leah's rate)
x+10 = 15 mph (May's rate)
