Question

rezolvatsi in mutimia n ecuatsia: A) 3(1-2x)+8=32 b) 60:(3y+2)=12 c) 1-3(8x-4)=1 d) 1605+4(3-x)=2011

Answer 1

a) 3×1-3×2x+8=32
3-6x+8=32
3-6x=24
6x=21. x=3,5
b)3y+2=5. 3y=3. y=1
c) 1-3.8x-3×4=1.
1-24x-12=1
1-24x=13
24x=12. x=0,5
d)1605+4×3-4x=2011
1605+12-12x=2011
12-12x=406
12x=394
x=32,8(3)
