Resolva as equações


me ajudem por favor!!
$a)3x - 3 = 9 \\ \\ b)x - 5 = 2 \times - 7 \\ \\ c)y - 6 = 6y + 9 \\ \\ d)10x = 20 + 9x \\ \\ e)2x + 5 = 5 - 4x \\ \\ f)3x + 10 = 7x - 6$

Answer 1

a) 3x-3=9

3x=9+3

x=12/3

x= 4

b) x - 5 =2x - 7

x - 2x = -7 + 5

-x = -2

x=2

c) y - 6 = 6y + 9

y - 6y = 9 + 6

-5y = 15

5y=15

y=15/5

y = 3

d) 10x = 20+9x

10x-9x = 20

x = 20

e) 2x + 5 = 5 - 4x

2x + 4x = 5 - 5

6x= 0

x= 0/6

x = 0

f) 3x + 10 = 7x - 6

3x - 7x = -6 -10

-4x = -16

4x = 16

x = 16/4

x = 4

Answer 2

a)x=2//b)x=7//c)3//d)20/...
