Question

equação do 1 grau incógnita


A)4x+2x=6+18

B)4x-6x=12+2

C)5x-8x=21

D)16y=4y+24

E)4y=-6y+30
​

Answer 1

a) 6x = 24

x = 24 ÷ 6

x = 4

b) -2x = 14

x = 14 ÷ (-2)

x = -7

c) -3x = 21

x = 21 ÷ (-3)

x = -7

d) 16y - 4y = 24

12y = 24

y = 24 ÷ 12

y = 2

e) 10y = 30

y = 30 ÷ 10

y = 3

Answer 2

Explicação passo-a-passo:

A)4x+2x=6+18

4x+2x=6+18

6x=24

x=24/6

x=4

B)4x-6x=12+2

4x-6x=12+2

-2x=14

x=14/-2

x=-7

C)5x-8x=21

5x-8x=21

-3x=21

x=21/-3

x=-7

D)16y=4y+24

16y=4y+24

16y-4y=24

12y=24

y=24/12

y=2

E)4y=-6y+30

4y=-6y+30

4y+6y=30

10y=30

y=30/10

y=3
