Question

gente, me ajuda nessas equações aqui? 

1. 4x-1=3 (x-1)

Answer 1

4x-1=3 (x-1)
  4x - 1 = 3x - 3
   4x-3x = - 3 + 1
    x = - 2

2. 3 (x-2)=2x -4==> 3x-6=2x-4==> 3x-2x=-4+6==>x=2
3. 7 (x-4)=2x-3==>7x-28=2x-3==>7x-2x=-3+28==> 5x=25==>x=5
4. 2(x-1)=3x+14==> 2x-2=3x+14==>3x-2x= -2-14==>x= - 16
5. 5 (x-2) = 4 (3-x)==>5x-10=12 -4x==>5x+4x=12+10==>9x=22==>x=22/9

Answer 2

1. 4x-1=3 (x-1)
4x-1=3x-3
4x-3x=-3+1
1x=-2
x=-2/1
x=-2
