Question

5(1-x)-2x+1=-3(2+x)

4x=-8x+36

2+3[x-3x+1)]=5[x-(2x-1)]

4(x-3)=2x-5

1-2x=x/3-x/2

3(x-1)-2x/5=5(x-3/6

2x+5/3x=1/4
Help please

Answer 1

mds eu juro ja fiz essa conta vou procurar aqui e posto

Answer 2

Explicação passo-a-passo:

5(1-x)-2x+1=-3(2+x)

5-5x-2x+1=-6-3x

-5x-2x+3x=-6-5-1

-4x=-12.(-1)

4x=12

x=12/4

×=3

4x=-8x+36

4x+8x=36

12x=36

x=36/12

x=3

2+3[x-3x+1)]=5[x-(2x-1)]

2+3x-9x+3=5x-2x+1

3x-9x-5x-2x=1-2-3

-13x=-6.(-1)

13x=6

x=6/13

x=0.46

4(x-3)=2x-5

4x-12=2x-5

4x-2x=-5+12

2x=7

x=7/2

x=3.5

1-2x=x/3-x/2

1/1-2x/1=x/3-x/2

MMC=6

6-12x=2x-3x

-12x-2x+3x=-6

-11x=-6.(-1)

11x=6

x=6/11

x=o.54

3(x-1)-2x/5=5(x-3/6)

3x-3-2x/5=5x-3/6

MMC=35

3x/1-3/1-2x/5=5x/1-3/6

105x-105-14x=175x-17.5

105x-14x-175x=-17.5+105

-84x=87.5.(-1)

84x=-87,5

x=87,5/84

x=1,04

2x+5/3x=1/4

MMC=12

2x/1+5/3x=1/4

24x+20x=3

44x=3

x=3/44

x=0,06

espero ter ajudado
