Question 94782
Let x=the integer

Then x+1=the next consecutive integer

2(x+1)=twice the next consecutive integer

Now we are told that:

x+2(x+1)=29  get rid of parens

x+2x+2=29  subtract 2 from both sides

x+2x+2-2=29-2  collect like terms

3x=27  divide both sides by 3
x=9-----------------------the integer
x+1=9+1=10------------------next consecutive integer

CK
9+2*10=29
29=29

Hope this helps-----ptaylor
