Question

Resolva as equações

A) X + 2 = 10

B) X - 6 = -8

C) 3x -21 = 0

D) 6+x = 64

E) 6 - 3x = -10 - 4x

F) 2(3x -5) = 14

Answer 1

A) X + 2 = 10
x=10-2
x=8

B) X - 6 = -8
x=-8+6
x=-2

C) 3x -21 = 0
3x=0+21
3x=21
x= 21/3
x= 7

D) 6+x = 64
x=64-6
x=58

E) 6 - 3x = -10 - 4x
3x+4x=-10-6
7x=-16
x=-16/7
x=−2.2857142857

F) 2.(3x -5) = 14
6x-10=14
6x=14+10
6x=24
x=24/6
x=4

Answer 2

A) x=10-2
x=8

B) x=-8+6
x=-2

C) 3x=21
x=21/3
x=7

D) x=64-6
x= 58

E) - 3x+4x= -10 - 6
x= - 16

F) 6x-10=14
6x= 14+10
x=24/6
x=4
