Question

ayuda porfa :( es para mañana​

Answer 1

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

Dividir ambos lados entre -2:

-2 (3x -2) = -2

      -2         -2

3x -2 = 1

3x = 1 +2

3x = 3

x = 3/3

x=1

2) 4x + 3 = 21 - 2x

4x + 2x = 21 - 3

6x = 18

x = 18/6

x = 3

3) 2(x + 1) - 3(x - 2) = x - 6

2x + 2 - 3x - 6 = x - 6

-x + 8 = x - 6

-x = x - 6 - 8

-x = x -14

-2x = 14

x = 7
