Question

Ejercicios:
1) 4X + 10 = 30
2) X- 4 = 16
3) 5X – 12 = 36 – X
4) X – 2 = 1

Answer 1

Respuesta:

1.-$4x + 10 = 30 \\ 4x = 30 - 10 \\ 4x = 20 \\ x = 5$

2.-$x - 4 = 16 \\ x = 16 + 4 \\ x = 20$

3.-$5x - 12 = 36 - x \\ 5x + x = 36 + 12 \\ 6x = 36 + 12 \\ 6x = 48 \\ x = 8$

4.-$x - 2 = 1 \\ x = 1 + 2 \\ x = 3$
