Question

решите уравнение 10,5:(y-3,6)=5,1:(y+1,8)

Answer 1

10,5:(y-3,6)=5,1:(y+1,8)

10,5*(y+1,8)=5,1*(y-3,6)

10,5y + 18,9 = 5,1y - 18,36

5,4y = - 37,26

y = - 6,9 

Answer 2

Решение:

10,5:(y-3,6)=5,1:(y+1,8)

10,5(y+1,8)=5,1(y-3,6)

10,5y+18,9=5,1y-18,36

10,5y+18,9-5,1y+18,36=0

5,4у+37,26=0

5,4y=-37,26

y=-6,9
