Answer:

X = >1

Step-by-step explanation:

We have the following imbalance in this situation: -3 + 5x < 7x - 5

7x is subtracted from both sides of the inequality, giving us:

The main sign is added after other signs are eliminated.

To both sides of the inequality, we add 3:

On both sides of the inequality, we divide by 2:

In order to account for the fact that the sense of inequality changes, we multiply by -1 on both sides:

All values of "x" larger than 1 provide the answer.

X = >1

For this case we have the following inequality:


-3 + 5x <7x-5

Subtracting 7x from both sides of the inequality we have:


-3 + 5x-7x <-5

Different signs are subtracted and the major sign is placed.


-3-2x <-5

We add 3 to both sides of the inequality:


-2x <-5 + 3\\-2x <-2

We divide between 2 on both sides of the inequality:


-x <\frac {-2} {2}\\-x <-1

We multiply by -1 on both sides taking into account that the sense of inequality changes:


x> 1

The solution is given by all the values of "x" greater than 1.

Answer:


x> 1
