write and solve an equation to answer the following questions

Question

find three consecutive integers such that the sum of the first and twice the second is equal to the third plus four?

Answer 1

3 consecutive numbers: x, x+1, x+2

x + 2(x+1) = (x+2) + 4

x + 2x +2 = x + 6

3x + 2 = x + 6

2x = 4

x = 2

Answer: 2, 3, 4
