Let x be the number. According to the problem, the first step is to add 5 to the number to get (x+5). Now, you need to double the result to get 2(x+5). This is equal to 22 less than the original number, which would be
x-22. So the equation to be solved is
2(x+5) = x-22
Distribute the 2 in front of the parentheses to get 2x + 10 = x-22
Subtract x from both sides to get x+10 =. -22
Subtract 10 from both sides to get the final answer, x = -32
