Tolong jawabkan (pilihan gandanya saja gak usah pake penyelesaian) 3-5

3) x - 1
----------- - 2 = 2
2

x - 1
------- = 2 + 2
2

x - 1
------- = 4
2

x - 1 = 4 • 2

x - 1 = 8

x = 8 + 1

x = 9 ( D )


4) ⅓x + 2/5 x = 22
5/15 x + 6/15 x = 22
11/15 x = 22
x = 22 ÷ 11/15
x = 22 × 15/11
x = 30 ( D )

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

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

3x - 9 = 4x - 8

3x - 4x = - 8 + 9

- x = 1

x = - 1 ( B )
