Answer:
15m +31
Step-by-step explanation:
5(3m+7) - 4 = 15m + 35 - 4 = 15m +31
For this case we have the following inequality:

To solve, we follow the steps below:
We divide between 5 on both sides of the inequality:

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

Thus, the solution is given by all values of "y" greater than or equal to 3.

Answer:
Step-by-step explanation:
4x -39 > -43 8x + 31 < 23
Add 39 to both sides Subtract 31 from both sides
4x -39 + 39 > -43 + 39 8x + 31 - 31 < 23 - 31
Simplify Simplify
4x > -4 8x < -8
Divide both sides by 4 Divide both sides by 8
4x / 4 > -4 / 4 8x / 8 < -8 / 8
Simplify Simplify
x > -1 x < -1
