Question

Помогите решить номер 430 (4-6)

Answer 1

4) s +13 - 2s = 2 + 5s - 37
s - 2s - 5s = 2-37 - 13
-6s = -48
s = -48/-6 = 48/6
s = 8.

5) 4 - 4v - 23 = 2v + 5 - 3v
-4v -2v + 3v = 5 - 4 + 23
-3v = 24
v = 24/-3
v = -8

6) 2x-3 - 5x = 5 + x - 36.
2x - 5x - x = 5 - 36 + 3
-4x = -28
x = -28/-4 = 28/4
x = 7.
