Question

3(1-2x)+8=32. 1-3(8x-4)=1. 60:(3y+2=12.
1605+4(3-x)=2011

Answer 1

3(1 - 2x) + 8 = 32
3 - 6x + 8 = 32
- 6x = 32 - 11
- 6x = 21
x = - 21/6
1 - 3(8x - 4) = 1
1 - 24x + 12 = 1
- 24x = 1 - 1 - 12
x = 12/24 = 1/2
60 : (3y + 2) = 12
60 = 12(3y + 2)
60 = 36y + 24
36y = 60 - 24
y = 36 : 36
y = 1
1605 + 4(3 - x) = 2011
1605 + 12 - 4x = 2011
- 4x = 2011 - 1605 - 12
- 4x = 394
x = - 394/4 = 197/2
