2(x-1)>3(2x-7)
2x-2>6x-21
2x>6x-21+2
2x-6x>-19
-4x>-19
-4x(-1)<-19(-1)
4x <19
x<19/4
∴ the greatest value of x is 4.
2x-2>6x-21
2x>6x-21+2
2x-6x>-19
-4x>-19
-4x(-1)<-19(-1)
4x <19
x<19/4
∴ the greatest value of x is 4.

2X-2 > 6X-21
2X-6X > -21+2
4X > -19
X < -19/-4
X < 19/4

2(X-1)>3(2X-7)
= 2X-2 > 6X-21
= 2X-6X > -21+2
= -4X > -19
= X < -19/-4
= X < 19/4
= 2X-2 > 6X-21
= 2X-6X > -21+2
= -4X > -19
= X < -19/-4
= X < 19/4
