Question

EQUAÇÕES:a) 3x+2-x=22+2
b) x+4=8
c)2x+x=13-1
d) 2t+t=31-1
e) x+2=8
f) 5x-10=20
g) 2x+2=10
Alguém pode me ajudar??

Answer 1

a 3x+2-x=22+2
3x-x=22+2-2
2x=22
x=11

b x+4=8
x=8-4
x=4

c 2x+x=13-1
3x=12
x=12/3

d 2t+t=31-1
3t=30
t=30/3
t=10

e x+2=8
x=8-2
x=6

f 5x-10=20
5x=20+10
5x=30
x=30/5
x=6

g 2x+2=10
2x=10-2
2x=8
x=8/2
x=4

Answer 2

Boa tarde Flavia

a) 3x+2-x=22+2 ,  2x = 22,  x = 11
b) x+4=8 ,  x = 8 - 4 = 4 
c)2x+x=13-1 , 3x = 12, x = 4
d) 2t+t=31-1 , 3t = 30, t = 10
e) x+2=8 , x = 8 - 2 = 6
f) 5x-10=20 , 5x = 20 + 10 = 30. x = 6
g) 2x+2=10 , 2x = 8, x = 4
