you could take care of inequalities extremely like equality signs and indicators with comprehend to the "including, subtracting, multiplying or dividing the two aspects" regulations ... as a consequence, you could divide out the two/3 from the two aspects, providing you with: 4x - 4 > sixteen / (2/3) = 4(x-4) > 3*sixteen/2 you could then divide out by utilising 4 on the two aspects: x-a million > 3*sixteen / (2*4) x-a million > 6 Then upload a million to the two aspects: x > 7
(2/3)(4x - 4) > 16
2(4x - 4)/3 > 16
8x - 8 > 3(16)
8x - 8 > 48
8x > 48 + 8
8x > 56
x > 56/8
x > 7
8x - 8 > 48
8x > 56
x > 7
{ x : x > 7 , x Є R }
if the equation is 2
----------------- >16
3(4x-4)
1
---------- > 16 *3/2
4x-4
1
----------- >24
4x -4
4x-4 > 1/24
4x > 1/24 + 4
4x> 97/24
x>97/96
2/3*4(x-1)>16
8/3(x-1)>16
x-1>6
x>7
2/3 (4x -4) > 16
(8/3)x-8/3>16
(8/3)x>16+8/3
(8/3)x>48/3+8/3
(8/3)x>56/3
(3/8)*(8/3)x>(56/3)*(3/8)
x>56/8
x>7
2/3 (4x -4) > 16
(4x -4) > 16(3/2) =24
4x > 24 + 4
4x > 28
x > 28/4
x > 7
