Question

Ayuda porfa soy corona si estan bien

Answer 1

a) 4x - 12 = 2x - 3

4x - 2x = - 3 + 12

2x = 9

x = 9/2

b) 7/4 x - 5 = 2x - 2

7/4 x - 2x = - 2 + 5

(-) - 0,25 x = 3

x = - 3/0,25

x = - 12

c) 2 (x-4)/2 + 2 (3/1) = 2 (4x/1)

1 (x-4) + 2(3) = 2 (4x)

x - 4 +6 = 8x

- 4 + 6 = 8x - x

2 = 7x

2/7 = x

d) x/2 - 5x = - 1 - 2

(-) - 4,5 x = - 3

x = 3/4,5

x = 2/3

Espero haberte ayudado. Saludos ≧◠◡◠≦.
