Question

2.(1-x)11=3(x-3)-2x

5(x+1)-3(2×+1)=4(5-x)

x-2(3-2x)=0

2(x-3)+6+4(x-5)=0

-3(4=2×)+x=-3-(9x-1)

-(4x-5)+2x=10-3(2×-4)

2(4-3x)-5(2x+1)=-7-3x

9x-3+4x=17+3-9

se puderem responder com os cálculos agradeço♡​

Answer 1

Explicação passo-a-passo:

(1-x)11=3(x-3)-2x

11-11x=3x-9-2x

11-11x=x-9

-12x=-9-11

-12x=-20

12x=20

x=20/12=10/6

5(x+1)-3(2x+1)=4(5-x)

5x+5-6x+3=20-4x

-x+8=20-4x

4x-x=20-8

3x=12

x=12/3

x=4

x-2(3-2x)=0

x-6-4x=0

-3x-6=0

-3x=6

-x=6/3

x=-2

2(x-3)+6+4(x-5)=0

2x-6+6+4x-20=0

6x-20=0

6x=20

x=20/6=10/3

-3(4-2x)+x=-3-(9x-1)

-12+6x+x=-3-9x+1

-12+7x=-2-9x

7x+9x=-2+12

16x=10

x=10/16=5/8

-(4x-5)+2x=10-3(2x-4)

-4x+5+2x=10-3x+12

-2x+5=22-3x

-2x+3x=22-5

x=17

2(4-3x)-5(2x+1)=-7-3x

8-6x-10x-5=-7-3x

3-16x=-7-3x

-16x+3x=-7-3

-13x=-10

x=10/13

9x-3+4x=17+3-9

13x-3=11

13x=11+3

13x=14

x=14/13
