Find three consecutive integers such that the sum of the second and the third is 17. Which equation would be used to solve this word problem?

a.) x + (x + 1) + (x + 2) = 17
b.)(x + 1) + (x + 2) = 17
c.)x + (x + 2) + (x + 4) = 17
d.) 2(x + 2) + 3(x + 4) = 17

    remember
    +x+=+
    -x-=+
    -x+=- and
    +x-=-

    a.
    X+(X+1)+(X+2)=17
    X+X+1+X+2=17
    NOTE: If there is no sign with variables (a,b,c ....z) or constant (1,2,3.......) then the sign will be automatically "+"
    3X+3=17
    3X=17-3
    X=14/3
    X=4.66666666666666
    X=4.67
