Answer:
52/3
Step-by-step explanation:
Use basic Thales therom,

Cross multiply,
3*(5x-8)=4*(3x+7)
3*5x - 3*8 = 4*3x + 4*7
15x - 24 = 12x +28
Add 24 to both sides
15x = 12x + 28 + 24
15x = 12x + 52
Subtract 12x from both sides
15x-12x =52
3x = 52
Divide both sides by 3
x = 52/3
Answer:
117 students, 8 adults
Step-by-step explanation:
Let's say a adults went and s students went.
Total cost for adults = 23 for each a = 23a
Total cost for each student = 16s
Number of adults and students = a + s = 125
Total cost = 23a + 16s = 2056
a + s = 125
23a + 16s = 2056
We can solve this by solving for a and then plugging that into the other equation, making it so that there is only one variable
subtract s from both sides in the first equation
a = 125 - s
plug that into the second equation
23(125 - s) + 16s = 2056
2875 - 23s + 16s = 2056
2875 - 7s = 2056
subtract 2875 from both sides to isolate s and its coefficient
-7s = -819
divide both sides by -7 to isolate s
s = 117
a = 125 - s = 125 - 117 = 8
