Question

Resolva as equações: a) 2 + x = 7
b) 3x – 24 = 0
c) 2 – 3x = – 9 – 4x
d) 6x = 2x + 16
e) 2x + 1 = 4x – 7
f) 2x – 4 = 17 – 2x + 1

Answer 1

A) x= 7 -2

x= 5

B) 3x= 24 + 0

3x = 24

x= 24/3

x= 8

C) -3x +4x = -9 +2

x = -7

D) 6x -2x = +16

4x= 16

x= 16/4

x= 4

E) 2x +4x = -7 -1

6x= -8

x= -8/6

F) 2x +2x= 17+1+4

4x= 22

x= 22/4
