Answer 1

1°) Resolva As Equações :
A) X + 2 = 8
X = 8-2
X= 6

B) X - 5 = 2
X= 2 + 5
X= 7

C) X + 3 = -2
X= -2 - 3
X= -5

D) X - 8 = - 10
X= -10 + 8
X = -2

E) 4X=20
X= 20/4
X= 5

F) X_3 = 6
X= 6+3
X=9

G) 5X + 3 = 13
5X=13-3
5x=10
X=10/5
X=2

H) X_3 - 10 = - 6
I ) 6X + 8 = 5X
6x-5x = -8
X = -8

J) 3X + 8 =5+2X
3x - 2x = 5 - 8
5x = -3
X = -3/5

K) 2X - 5 = 7 + 5 X
5x - 2x = 7 + 5
7x = 12
X = 12/7
