Question

RESUELVE LAS SIGUIENTES ECUACIONES CON VALOR a) [ x-1] = 2×-1
b) 2×+|×1| = 2
c) [ 3×+7| = 5×+|3​

Answer 1

Respuesta:

a ) x = 0

b ) x = 1

c ) x = 2

Explicación paso a paso:

a )

[ x - 1 ] = 2x - 1

2x - 1 = x - 1

2x - x = - 1 + 1

x = 0

b )

2x + l x 1 l = 2

2x = 2

x = 2 / 2

x = 1

c )

3x + 7 = 5x + 3

5x + 3 = 3x + 7

5x - 3x = 7 - 3

2x = 4

x = 4 / 2

x = 2
