Question

2(x+1)-(x-1)=0 B- 5(X+1)-3(X+2)=0 C-13+4(2x-1)=5(x+2) D- 2(X+5)-3(5-X)=10 E- 8(X-1)=8-4(2X-3) AJUDEM PFV

Answer 1

2(x+1)-(x-1)=0

2x+2-x+1=0

2x-x=-2-1

x=-3

5(x+1)-3(x+2)=0

5x+5-3x-6=0

5x-3x=6-5

2x=1

x=2

-13+4(2x-1)=5(x+2)

-13+8x-4=5x+10

8x-5x=10+4+13

3x=27

x=9

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

2x+10-15+3x=10

2x+3x=10-10+15

5x=15

x=3

B) x=1 sobre 2

C) x= -1 sobre 2

D) x=3

E) x=7 sobre 4
