Question

The sum of three consecutive whole numbers is 96.If the lowest number is y then:
a)write down an expression for the other two numbers in terms of y.
b)write down an equation involving y.
c)find y and hence find the other two numbers.

Answer 1

a) y+1 is the next number and the third number is y+2
b) y + (y+1) + (y+2) = 96 , that is the smallest plus the next plus the next :)
c) your turn to solve for y
step1:
y + y + 1 + y + 2 = 96

Answer 2

y + y + 1 + y + 2 = 96
y + y + y = 96-1-2
3y = 93
y= 93,3
y= 31
Is it correct?

Answer 3

3y = 93,
Y = 31.
