Question

RESOLVA AS EQUAÇÕES DO 1° GRAU

Answer 1

a) 5x + 5 = 25

5x = 20

x = 20 / 5

x = 4

b) 4x + 4 = 20

4x = 16

x = 16 / 4

x = 4

c) (2x + 6) / 2 = 4

2x + 6 = 8

2x = 2

x = 2 / 2

x = 1

d) 11x - 6 = 9x + 78

11x - 9x = 78 + 6

2x = 84

x = 84 / 2

x = 42

Answer 2

A)5x= 25- 5
5x= 20/5
x4

B)4x=20+4
4x= 24/4
x= 6

C) Irei resolver


D) 11x -9x=78+6
2x=84/2
x=42
