Question

me ajudem????

9x+32=8x-33

2.(x-3)=-(5x-4)

1-x=29+6x

2.(x-16)=8

Answer 1

Bom dia!

9x +32 = 8x -33

9x -8x = -33 -32

x = -65

_____________

2(x-3)=-(5x-4)

2x -6 = -5x +4

2x +5x = 4 + 6

7x = 10

x = 10/7

______________________

1 - x =29 +6x

-x -6x = 29 -1

-7x = 28 (-1)

7x = -28

x = -28/7

x= -4

_______________

2(x-16) = 8

2x -32 = 8

2x = 8+32

2x = 40

x = 40/2

x = 20
