Solve:
12+46x−1<4
5−6x+7less than or equal to 17
...can you please explain to me..
i know that it's like solving algebraically but one of them has no solution..

1. 12 + 46x1 < 4.
46x1 < 412
46x1 < 8
6x1 < 2
6x  1 < 2
6x < 2+1
6x < 1
X < 1/6.
The calculated value of X does not satisfy the inequality. Make sure the problem is copied correctly.
2. 5 6x+7 <= 17
6x+7 <= 175
6x+7 <= 12
x+7 >= 2
x+7 >= 2
X >= 27
X >= 9.
