preciso pra hj alguém por favor​

Answer 1

Resposta:

a)x + 5 = 8 => x=8-5 => x=3

b)x - 4= 3=>. x=7

c)x + 6 = 5=> x=-1

d)x - 7-7=>. x=17

e)X + 9 = -1. =>. x=-10

f)x - 39-79=> x=118

g)10 = x + 8=> x=2

h)15 = x + 20 => x=-5

i)4 = x - 10=>x=14

j)7 = x + 8=> x=-1

k)x - 1 = 5=>x=6

l)2x + 4 = 16=>x=6

m)3x = 15=>x=5

n)2x = 10=>x=5

0)3x = -9=>x=-3

p)2x - 2 = 12 - 5x=> x=14/7=2

q)3x - 13 =8=> x=21/3=7

r)4x - 9=23=> x=32/4=8

s)7x - 33 -12=> x=45/7

t)33+ X =5 - 3x=> x=-28

u)2x = 14=>v x=7

v)7x = -21=> x=-3

w)4x= -12=> x=-3

X)35x-105. =>x=-3
