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.

natali 33 [55]

Answer:

x = -4

Step-by-step explanation:

–2x + 1 – (–7x + 3) = –4 + 3(x – 2)
