Question

x - 3[x - 2]=6x - 2
Explicación
3x - 7=2[x+1]
Explicación ​

Answer 1

Primer problema:

[tex]X - 3[x - 2]=6x - 2:x=1[/tex]

[tex]x-3\left[x-2\right]-6x=6x-2-6x\\\\-8x+6=-2\\\\-8x+6-6=-2-6\\\\-8x=-8\\\\\frac{-8x}{-8}=\frac{-8}{-8}\\\\x=1[/tex]

Segundo problema:

[tex]3x - 7=2[x+1]:x=9\\\\3x-7+7=2\left[x+1\right]+7\\\\3x=2x+9\\\\3x-2x=2x+9-2x\\\\x=9[/tex]
