Question

Solve the inequality X+ 7 < 4x+ 25 The solution is x​

Answer 1

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 $x > -6$.
