Answer:
balloons= 9
candles= 8
Step-by-step explanation:
let the number of balloons be x
and candles be y
So
15x+8y=192----------1
x+y=17--------------2
from 2, x= 17-y
put x= 17-y in 1
15( 17-y)+8y=192
255-15y+8y=192
solve for y
-7y=192-255
-7y=-63
x=63/7
x=9
put x= 9 in 1
9+y=17
y= 17-9
y=8.

x = 14
Step-by-step explanation:
Given

Multiply both sides by 3 to clear the fraction
2(x + 4) = 36 ( divide both sides by 2 )
x + 4 = 18 ( subtract 4 from both sides )
x = 14
