Let the number = x
So we have:
the sum of double a number,one-third of the number and eight times the number is 155.Find the number. Well we know the numbers are added because of the word SUM.
double a number= 2x
1%2F3 a number = 1%2F3x
eight times a number = 8x
So when added together thwey =155
2x+1%2F3x+8x=155
10x+1%2F3x=155
31%2F3x=155
x=155%283%2F31%29
x=465%2F3
x=15
Hope you understand
