Question

EQUAÇÃO DO 1 GRAU:URGENTE PFV
A)2(X+1)=8
B)3(X-1)=8
C)2(1+X)=-6
D)5(X+1)=35
E)4(1+X)=4
D)2(1+X)=2
E)7+2(X-1)=X
F)6+3(X-1)=2X
G)9-(1-X)=0
H)-6+4(X-1)=2
I)9-2(X+10)=X
J)8X-(1-X)=-1

Answer 1

a) 2x + 2 = 8

x = 3

b) 3x - 3 = 8

x = 5/3

c) 2 + 2x = -6

x = -2

d) 5x + 5 = 35

x = 6

d) 2 + 2x = 2

x = 0

e) 7 + 2x - 2 = x

x = -5

f) 6 + 3x - 3 = 2x

x = -3

g) 9 - 1 - x = 0

x = 8

h) -6 + 4x - 4 = 2

x = 3

i) 9 - 2x - 20 = x

-x = 11

x = -11
