Question

Resolver : estos ejercicios no los puedo resolver me podrian ayudar?
aº- 5(x-1)+16(2x+3)=3 (2x - 7 ) -x
bº- ⅗ + 3/2x -1
cº- 2(3x+2)-4(5x - 3 ) = x (x-3) - x (x+5)
dº- 2/4x-1 = 3/4x + 1

Answer 1

A) 5x-5+32x+48=6x-21-x
37x+43=5x-21
37x-5x=-21-43
32x=-64
x=-64/32
x=-2

b) 3/5 + 3/2 x - 1 = 0
3/2 x = 1- 3/5
3/2 x = 2/5
x= (2/5)*(2/3)=4/15

c)6x+4-20x+12=x^2 -3x -x^2 -5x
-14x+16=-8x
14x-8x=16
6x=16
x=16/6=8/3

d) -2/4 x + 3/4 x =-1-1
1/4 x= -2
x=-2*(4/1) =-8

Espero te sirva! ^--^
