Question

3 (x - 2 )=4 (3-x)
3 (3 x -1 ) = 2 (3 x + 2 )
7 ( x - 2 )= 5 (x+ 3 ) ​

Answer 1

Explicação passo-a-passo:

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

3x-6=12-4x

3x+4x=12+6

7x=18

x=18/7

3 (3 x -1 ) = 2 (3 x + 2 )

9x-3=6x+4

9x-6x=4+3

3x=7

x=7/3

7 ( x - 2 )= 5 (x+ 3 )

7x-14=5x+15

7x-5x=15+14

2x=29

x=29/2

Answer 2

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

3x - 6 = 12 - 4x

3x + 4x = 12 + 6

7x = 18

x = 18/7

3(3x - 1) = 2(3x + 2)

9x - 3 = 6x + 4

9x - 6x = 4 + 3

3x = 7

x = 7/3

7(x - 2) = 5(x + 3)

7x - 14 = 5x + 15

7x - 5x = 15 + 14

2x = 29

x = 29/2
