M an is 72_xy=2 because I saw it on calculator and it showed
-8t+6+6t=5t-2
-2t+6=5t-2
-2t-5t=-2-6
-7t=-8
-7 -7
T=1.14 or 1 1/7
S = 25 + 2f
s + f = 310
substitute s = 25 + 2f into the second equation
25 + 2f + f = 310
3f + 25 = 310
subtract 25 from both sides
3f = 285
divide both sides by 3
f = 95
faculty = 95
students = 310 - 95 = 215
