Question

ayuda plis(doy corona) 3×+1=×1​

Answer 1

Respuesta:

-1 y - 7/5

Explicación paso a paso:

3x + 1 = x - 1

3x - x = - 1 - 1

2x = - 2

x = - 2/2

x = - 1

Verificacion :

3(-1) + 1 = (-1) - 1

- 3 + 1 = - 2

- 2 = - 2

5(2x + 3) = 5x + 8

10x + 15 = 5x + 8

10x - 5x = - 15 + 8

5x = - 7

x = - 7/5

Verificacion :

10(-7/5) + 15 = 5(-7/5) + 8

- 14 + 15 = - 7 + 8

+ 1 = + 1
