Resolva;
A) x-3 = 5
B) 6x-4 = 2x+8
C) x+2 = 7
D) -3 = x+10
E) 15 = x+1
F) 3x = 12
G) x/5 = 2
H) 0 = x+12

Answer 1

A)x-3= 5
x =5+3
x=8

B)6X-4 = 2x+8
6x-2x=4+8
4x=12
x=12/4
x=3

C)x+2 =7
x= 7-2
x=5

D)-3=X+10
X=3+10
x=13

E)15= x+1
15-1=x
14=x

F)3x=12
x=12/3
x=4

G)x/5=2
x=2•5
x=10

H)0=X+12
0-12=x
12=x

Espero ter ajudado!!!
