inequality Express y 8x 2 7x 4 H 13 1211 SolutionSolving t

inequality. Express y 8x 2> 7x - 4 H- 13 -12-11 -

Solving the inequality

=> 8x+2 > 7x-4

.........................: subtract 7x from both sides we get

=> 8x-7x+2 > 7x-7x-4

........................+7x and - 7x cancel out on right side to make 0

.........................and 8x-7x become 1 x (combining like terms )

=> 1x+2>-4

..........................Subtract 2 from both sides

=> 1x+2-2 >-4-2

.................+2 and -2 cancel out to get 0

=> 1x >-6

=> x>-6

So the answer is B
