Question

Ajutama 3x-9+x=2x-27
8x-5x+32=2x-51
3x+(255-62)=23

Answer 1

Salut!:

a) 3x - 9 + x = 2x - 27

4x - 9 = 2x - 27

2x = -18

x = -9

b)8x - 5x + 32 = 2x - 51

3x + 32 = 2x - 51

x = -83

c) 3x + ( 255 - 62 ) = 23

3x + 193 = 63

3x = -130

x = -130 / 3

Bafta!:)

Answer 2

Explicație pas cu pas:

3x-9+x=2x-27

4x-9=2x-27

4x-9-2x+27=0

2x+16=0

2x=-16

x=-8

8x-5x+32=2x-51

3x+32=2x-51

3x+32-2x+51=0

x+83=0

x=-83

3x+(255-62)=23

3x+193=23

3x=23-193

3x=-170

x=-170/3
