Question

A- x=10
B- 20x-33=7
C- -900x-1=1799
D- 15x-29=1
E- 6x-8=4
como resolver?

Answer 1

A) x = 10 (já está resolvido ksks)

B) 20x - 33 = 7

20x = 7 + 33

20x = 40

x = 40 / 20

x = 2.

C) -900x -1 = 1799

-900x = 1799 + 1

-900x = 1800

x = 1800 / (-900)

x = -2.

D) 15x -29 = 1

15x = 1 + 29

15x = 30

x = 30 / 15

x = 2.

E) 6x -8 = 4

6x = 4 + 8

6x = 12

x = 12/ 6

x = 2.
