Решите уравнения:
63-8с=с
7х + 17 = х - 1
-14 + (х-17)= -4
-(25-у) + 60 = 48
(х - 5) - (2-2х) = 6
-(3х + 5) + (4-7х) = 4
-4х + 1 =13

Заранее спасибо.

63 - 8с = с63 = с + 8с63 = 9сс = 63 : 9с = 77х + 17 = х - 17х - х = -1 - 176х = -18х = - 18 : 6х = -3-14 + (х-17)= -4-14 + х - 17 = -4х = -4 +17 + 14х = 27-(25-у) + 60 = 48-25 + у + 60 = 48у = 48 - 60 +25у = 13(х - 5) - (2-2х) = 6х - 5 - 2 +2х = 6х + 2х = 6 + 2 + 5 3х = 13х = 13 : 3 = 4 -(3х + 5) + (4-7х) = 4-3х - 5 + 4 - 7х = 4-3х -7х = 4 - 4 + 5-10х = 5х = -5 : 10х = -0,5-4х + 1 = 13-4х = 13 - 1-4х = 12х = - 12 : 4х = -3
