c(30x): (5x5) =
d (6x2 - 3): (3x.) -
e) (9x+y- 6xy - x y): (3xºy)​

Answer 1

Explicação passo-a-passo:

a)4x+2x=9+4

6x=13

x=6÷13

x= 0,46

b)6x+x-5x=3-3

2x=0

x=2÷0

x=1

c)2x+8x=4-3

10x=1

d)2x-4x=6-3+5

-2x=8

2x=-8

x=-8÷2

x =-4

e)5x-7x=10-2

-2x=8

2x=-8

x =-8÷2

x=-4

f)6x-3x+x=8+7

4x=15

x=15÷4

x=3,75

g)7x+3x=5-14

10x=-9

x=-9÷10

x=-0.9

h)5x+2x-4x=8-3

3x=5

x=5÷3

x=1.666....

i)3x+2x=9-3

5x=6

x=6÷5

x=1.2

j)3x+2x=9-3

5x=6

x=6÷5

x=1.2

k)12x-7x=6-7

5x=-1

x=-1÷5

x=0.2
