Question

resolver la siguiente la ecuacion

1) X + 5 = 9
2)X - 3 = 10
3)2X = 14
4) 5X + 1 = 21 ​

Answer 1

1)

x + 5 = 9

x = 9 - 5

x = 4

---------------------------------

2)

x - 3 = 10

x = 10 + 3

x = 13

---------------------------------

3)

2x = 14

x = 14/2

x = 7

---------------------------------

4)

5x + 1 = 21

5x = 21 - 1

5x = 20

x = 20/5

x = 4
