Question

Решите уравнение.Решение и ответ.

Answer 1

Х - 2 = 3
х = 3+ 2
х = 5
--------------------
5 + 3у = - 28
3у = -28 - 5
3у = - 33
  у = - 11
--------------------
3х = 5(х + 2)
3х = 5х + 10
3х - 5х = 10
-2х = 10
   х = - 5
---------------------
3(z + 1) = 2z
3z + 3 = 2z
3z - 2z = -3
z = - 1
----------------------
s - 3 - 2s = 0
s - 2s = 3
-s = 3
s = - 3
