How do you solve 3x+7-(3-x)=(x+2)+x
I really don't understand this so if someone can please help me I would really be pleased. THANK YOU!!!!
3x + 7 - (3 - x) = (x + 2) + x
3x + 7 - 3 + x = x + 2 + x
4x + 4 = 2x + 2
4x + 4 - 2x = 2x + 2 - 2x
2x + 4 = 2
2x + 4 - 4 = 2 - 4
2x = -2
2x / 2 = -2 / 2
x = -1
