Step-by-step explanation:
6y+9=18
6y=2
y=1/3
Answer:
Step-by-step explanation:
Let first group of people take x candies each
and second group of people take y candies each
5x + 7y will be total candies
5x +7y = 239 (needed to find positive solution of x,y)
now take x=38, y =7
or x=31, y= 12
hence lots of possibilities ,so we can not say exactly
1.) 50 - 14 = 4x
x = 50 - 14 divided by 4 = 36/4 = 9.
x = 9
2.) 6(3x) -12 + 5x = 57
18x + 5x = 57 + 12
23x=69
x = 69 divided 23 = 3
x = 3
