Question

РЕШИТЕ ПОЖАЛУЙСТА УРАВНЕНИЯ:

а)5х+(3х-3)=6х+11
б)5(3у-4)=20у-10
в)1/6у-1/2=3-1/2у
г)-9х=-3

Answer 1

A) 5X + 3X - 3 = 6X + 11

8X - 3 = 6X + 11

2X = 14

X = 7

Б) 15Y - 20 = 20Y - 10

5Y = - 10 

Y = - 2

B) 16Y + 12Y = 3 + 12

16Y + 36Y = 72

46Y = 72

23Y = 72

4Y = 21

Y = 5.25

G) - 9X = - 3

X = - 3 : (-9)

X = + 13
