Question

Ayuda por favor , me podrian ayudar y explicar?

Answer 1

2x-1 = 6

2x = 6+1

2x = 7

x = 7/2

Answer 2

Resolver.

2x/3 - 1 = 3
2x /3 = 3 + 1
2x/3 = 4
2x = 4 * 3
2x = 12
x = 12/2
x = 6

Pero si el ejercicio es asi

2x - 1/2= 3
2x = 3 + 1/2
2x = 6/2 + 1/2
2x = (6 + 1)/2
2x = 7/2
x = 7/(2 * 2)
x = 7/4
