CAN SOMEONE HELP ME WITH MY MATH PROBLEM PLEASE I'VE BEEN STUCK ON THIS FOR A WHILE Subtract a number from -2 so that the difference is equal to: the numerical reciprocal of -2

The NR of -2 is -0.5. So you would need to subtract -2.5

The reciprocal of -2 would be 1/2, so to subtract a number from -2 to equal 1/2 we should put it in an equation

-2 - x = 1/2
Now cancel out the -2 by adding 2

-x = 2 1/2
Then multiply -x by -1 and do the same on the other side

X= -2 1/2

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
