We define x as the number that we are looking for

now, we will write the equation following the conditions that they give us


4-x=17

Now we pass -x to the right with opposite sign, and 17 to the left with opposite sign


4-17=x

The we solve the substraction and we have


x=-13

Finally, we can check if our answer actually fulfill the conditions given below


4-(-13)=\text{ 17}
