Question

1-3(8х-4)=1 60:(3у+2)=12 1605+4(3-х)=2011

Answer 1

1.
1-24x+12=1
13-24x=1
24x=12
x=0.5

2.
20y+30=12
20y=12-30
20y=-18
y=-18/20
y=-9/10

3.
1605+12-4x=2011
1617-4x=2011
4x= -394
x=-98.5

Answer 2

1-3(8x-4) = 1 + 60/(3y+2) = 12 + 1605 + 4(3-x) = 2011

Давайте посчитаем каждое уравнение по очереди.

1. 1-3(8x-4) = 1 1-24x+12 = 1 -24x+12 = 0 -24x = -12 x = 1/2

2. 1 + 60/(3y+2) = 12 60/(3y+2) = 11 60 = 11(3y+2) 60 = 33y + 22 33y = 38 y = 38/33

3. 2011 + 4(3-x) = 2011 2011 + 12 - 4x = 2011 2023 - 4x = 2011 -4x = 2011 - 2023 -4x = -12 x = 3

Итак, решения уравнений: x = 1/2 y = 38/33 x = 3
