A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. For example, crumbling up a piece of paper. It’s still a piece of paper and you uncrumble it and it is still paper.
4m - 7n = 10
2m + 2n = 4 - multiply everything by -1.
4m - 7n = 10
-2m - 2n = -4 Add the 2 equations
(4m - 7n = 10)
+(-2m - 2n = -4)
-------------------------
2m - 9 n = 6.
The value of 2m - 9n would be 6.
