Question

resolva as equaçoes

A) 4x-6=22
B) 9-x=2x
C) 8+4x=6x-4
D) 3X=1=X+9
E) 4x-11=7-2x
F)13x+1-10x=5+X

Answer 1

a) 4x - 6 = 22
4x = 22 + 6
4x = 28
x = 28/4
x = 7

b) 9 - x = 2x
2x + x = 9
3x = 9
x = 9/3
x = 3

c) 8 + 4x = 6x - 4
6x - 4x = 8 + 4
2x = 12
x = 12/2
x = 6

d) 3x + 1 = x + 9
3x - x = 9 - 1
2x = 8
x = 8/2
x = 4

e) 4x - 11 = 7 - 2x
4x + 2x = 7 + 11
6x = 18
x = 18/6
x = 3

f) 13x + 1 - 10x = 5 + x
13x - 10x - x = 5 - 1
2x = 4
x = 4/2
x = 2

Espero ter ajudado.

Answer 2

Ola

a)
4x - 6 = 22
4x = 28
x = 28/4 = 7

b)
9 - x = 2x
9 = 3x
x = 9/3 = 3

c)
8 + 4x = 6x - 4
6x - 4x = 8 + 4
2x = 12
x = 12/2 = 6

d)
3x - 1 = x + 9
3x - x = 9 + 1
2x = 10
x = 10/2 = 5 

e)
4x - 11 = 7 - 2x
4x + 2x = 7 + 11
6x = 18
x = 18/6 = 3

f)
13x + 1 - 10x = x + 5
13x - 10x - x = 5 - 1
2x = 4
x = 4/2 = 2
