Answer:

x > -6

Step-by-step explanation:

Solve the following inequality:

x + 7 < 4x + 25

-Take 4x and subtract it from x :

x - 4x  + 7 < 4x - 4x + 25

-3x + 7 < 25

-Subtract 7 on both sides:

-3x + 7 - 7< 25 - 7

-3x < 18

-When you are dividing an integer by a negative integer, then the inequality sign changes. So, Take -3x and divide it on both sides:

\frac{-3x}{-3} < \frac{18}{-3}

x > -6

Therefore, the answer is x > -6.
