Question

Resuelve las siguientes ecuaciones y verifica su resultado

1) 17 - x = 5
2) x:6 = 7
3) 7 + 8x = 28 + 5x
4) 8x - 5 = 5x + 13
5) x³ - 2 = 25​

Answer 1

Respuesta:

1) 17- x = 5

x = 5 + 17

x = 22

2)x : 6 = 7

x = 7.6

x=42

3) 7+8x = 28+5x

8x-5x = 28-7

3x = 21

x = 21:3

x = 7

4) 8x-5 = 5x+13

8x-5x = 13+5

3x = 18

x = 18:3

x = 6

5) x³-2 = 25

x-2 = √25

x-2 = 5

x = 5+2

x = 7
