Question

ola alguém ai ajundd 1)resolva. a)2x-6=10 b)9x=3x+24 c)5x-3=-13 d)5x=27-4x e)20x-9=11x f)8y -1=5y resolvA.:

Answer 1

a) 2x-6=10
2x=10+6
2x=16
x=16/2
x=8

b) 9x=3x+24
9x-3x=24
6x=24
x=24/6
x=4

c) 5x-3=-13
5x=-13+3
5x=-10
x=-10/5
x=-2

D) 5x=27-4x
5x+4x=27
9x=27
x=27/9
x=3

E) 20x-9=11x
20x-11x=+9
9x=9
x=9/9
x=1

F) 8y-1=5y
8y-5y=1
3y=1
y=1/3

Espero ter ajudado (:

Answer 2

Resposta:

a) 8

b) 4

c) -2

d) 3

e) 1

f) 1/3

Explicação passo-a-passo:

a) 2x - 6 = 10

2x = 10 + 6

2x = 16

x = 16 / 2

x = 8

------------------------------------

b) 9x = 3x + 24

9x - 3x = 24

6x = 24

x = 24 / 6

x = 4

------------------------------------

c) 5x - 3 = -13

5x = -13 + 3

5x = - 10

x = -10 / 5

x = -2

-------------------------------------

d) 5x = 27 - 4x

5x + 4x = 27

9x = 27

x = 27 / 9

x = 3

-------------------------------------

e) 20x - 9 = 11x

20x - 11x = 9

9x = 9

x = 9 / 9

x = 1

------------------------------------

f) 8y - 1 = 5y

8y - 5y = 1

3y = 1

y = 1 / 3
