There are a multitude of additions that could result in -7. Adding a negative number is basically the same as changing the plus sign to a minus, then doing the subtraction as if you were subtracting positive numbers. Adding a positive number to a negative number makes the number move closer to 0 (or past it if the positive number is larger). Also, adding two negative numbers results in a negative number.
0 + -7 = -7
2 + -9 = -7
-8 + 1 = -7
-3 + -4 = -7
If: A+7 = -3 then A = -10
Positive 4 -3 + 7= 4 Negative 3 plus positive 7 equals positive 4.
4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)
-7 = (-11 +x ) -7 -x = -11 x= 4
