According to the question we have the following data:

the sum of 12 and x is -7

This problem can be resolved by formulating the following equation:

if the sum of 12 and x is -7 that means that:


12\text{ + x=-7}

Therefore, to calculate x we would have to make the following:

12 + x=-7

x=-7-12

x=-19

If x is -19 then if we substitue this value in the original equation we would find that the result is correct:

the sum of 12 and x is -7

12 +(-19)=-7
