Question

Olá, podem resolver essas questões para mim?

a) 3x+5-x=17-2x-2+x
b)y+3y+5-y=16-y+13
c)4x+2-x=17-2x-15
d)2x+7-3x=10-x+12+3x
e)6+2x-3=5-3x+1
f)4-2x=10-3x+5
g)4-3x+5=16-2x+7
h)6-2x+3=17-3x+5
i)3x-6-7x=3-2x+4
j)3x-4+2x=-6-7x-3

Answer 1

a) X = 10/3

b) Y= 6

c) X= 0

d) X= 15/4

Answer 2

a)3x+5-x=17-2x-2+x

2x+5=-1x+15

3x=10

x=10/3

b)y+3y+5-y=16-y+13

3y+5=29-y

4y=24

y=24/4

y=6

c)4x+2-x=17-2x-15

3x+2=2-2x

5x=0

x=0/5

x=0

d)2x+7-3x=10-x+12+3x

-1x+7=2x+22

-3x=15

x=15/-3

x=-5

e)6+2x-3=5-3x+1

2x+3=-3x+6

5x=3

x=3/5

f)4-2x=10-3x+5

-2x+4=-3x+15

x=11

g)4-3x+5=16-2x+7

-3x+9=-2x+23

-x=14

(multiplica por -1 pois não existe uma incógnita negativa)

x=-14

h)6-2x+3=17-3x+5

-2x+9=-3x+22

x=13

i)3x-6-7x=3-2x+4

-4x-6=-2x+7

-2x=13

x=-13/2

j)3x-4+2x=-6-7x-3

5x-4=-7x-9

12x=-5

x=-5/12

Espero ter ajudado um forte abraço!!
