5x = 25 + 2x 2x -6= 8x +5 3x-4= 2x +1 3x +12 = 7x -8 6x -4=3x +5

[tex]5x = 25 + 2x \\ 5x - 2x = 25 \\ 3x = 25 \\ x = 8.3 \\ [/tex]
[tex]2x - 6 = 8x + 5 \\ 2x - 8x = 5 + 6 \\ - 6x = 11 \\ x = - 1.83[/tex]
[tex]3x - 4 = 2x + 1 \\ 3x - 2x = 1 + 4 \\ x = 5[/tex]
[tex]3x + 12 = 7x - 8 \\ 3x - 7x = - 8 - 12 \\ - 4x = - 20 \\ x = 5[/tex]
[tex]6x - 4 = 3x + 5 \\ 6x - 3x = 5 + 4 \\ 3x = 9 \\ x = 3[/tex]
maaf kalo ada yg salah ^^
