Question

resolva as equações A)2X-4-8=4X B)3x=X+1+7 C)360+36X=30X D)2X+5-5X=-1

Answer 1

(a) 2x - 4 - 8 = 4x
-4 - 8 = 4x - 2x
-12 = 2x
-12/2 = x
-6 = x

(b) 3x = x + 1 + 7
3x - x = 1 + 7
2x = 8
x = 8/2
x = 4

(c) 360 + 36x = 30x
36x - 30x = -360
6x = -360
x = -360/6
x = -60

(d) 2x + 5 - 5x = -1
2x - 5x = -1 - 5
-3x = -6
x = -6/-3
x = 2



Espero ter ajudado.
Bons estudos! :)

Answer 2

A) 2x-4-8=4x

2x - 12 = 4x

2x - 4x = 12

-2x = 12

X = -6

B) 3x=x+1+7

3x = x = 8

3x - x = 8

2x = 8

X = 4

C) 360+36x=30x

36x - 30x = -360

6x = -360

X = -60

D) 2x+5-5x= -1

-3x+5 = -1

-3x = -1 -5

-3x = -6

X = 2
