Question

the sum of three consecutive integer is 88. identify the variable and write an equation the describes the situation.

Answer 1

Lets say that you take n as the integer. Now you'll add it with 3 numbers. n+(n+1)+(n+2)=88. Now add 'em up, the sum is 3n+3=88. Take the 3 to the other side and subtract it from 88 which is 85. Now it'll be n= 85/3
