Question

Resolver las ecuaciones como el primer ejemplo.

Answer 1

5 + 3x - 8 + 2x = 22

5x - 3 = 22

5x = 22+3

5x= 25

x= 25/5

x= 5

-9x - 9 =72

-9 -72 =9x

-81 = 9x

-81/9 = x

-9 =x

8y - 4 + 3y = 7y + y + 14

11y - 4 = 8y + 14

11y - 8y= 14+4

3y= 18

y= 18/3

y= 6

10x -3 + 5 = 5x

10x + 2 = 5x

10x - 5x = -2

5x = -2

x= -2/5

• en decimales: -0.4

2x - 10 = 4x - 36

-10 + 36 = 4x - 2x

26 = 2x

26/2 = x

13 = x
