Resolva as equaçoes abaixo:
a)2+x=7
b)7x=49
c)5x+7(x+4)=172
d)x-3
____ =2
11
e)x-x
-- +3=11
3
f)3x-24=0

Obs: pra hoje

Answer 1

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

b)7x=49
x=49/7
x=7

c)5x+7 (x+4)=172
5x+7x+28=172
12x=172-28
x=144/12
x=12

d) x-3
--------- = 2
11

x-3=2*11
x=22+3
x=25

e) x-x
--------- + 3=11
3

x-x +3= 11*3
x-x=33-3
x-x= 30

f) 3x-24=0
3x=24
x=24/3
x=8

Bons Estudos!!
