Question

Resolva as seguintes equações(por favor me ajudam)

A) 2x + 3 = 11
B) 5x - 8 + 2= 14
C)2x + 3= 2 - x
D)4x - x - x = 24 - 12
E)4x - 6 = 22
F) 9 - x = 2x
G)8 + 4x = 6x - 4
H)3x + 1 = x + 9
I)4x - 11 = 7 - 2x
J)13x + 1 - 10x = 5 + x

Answer 1

A) 2x + 3 = 11 > 2x = 11-3 > 2x = 8 > x = 8/2 > x = 4

B) 5x - 8 + 2 = 14 > 5x - 6 = 14 > 5x = 14+6 > 5x = 20 > x = 20/5 > x = 4

C) 2x + 3 = 2 - x > 2x + x = 2 - 3 > 3x = -1 > x = -1/3

D) 4x - x - x = 24-12 > 2x = 12 > x=12/2 > x = 6

E) 4x - 6 = 22 > 4x = 22 + 6 > 4x = 28 > x = 28/4 > x = 7

F) 9 - x = 2x > 9 = 2x + x > 9 = 3x > 9/3 = x > 3 = x > x = 3

G) 8 + 4x = 6x - 4 > 8 + 4 = 6x - 4x > 12 = 2x > 12/2 = x > 6 = x > x= 6

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

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

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