Question

1. Solve 4x + 5 > 5x – 2 for x.

Answer 1

The answer should be X < 3 !

Explanation:

You first minus 5 to the other side which gave you -3 . Then you minus the 5x to the other side which gave you -1. After than just need to divide -1 to both side, switch the > and you’ll get the answer! Hope the explanation makes sense.

Answer 2

Greetings.

By solving an Inequality is almost the same as solving an equation.

We simply move x-term to the same term and the number or rather a constant to the same side.

$4x - 5x > - 2 - 5 \\ - x > - 7$

A quick reminder. If the coefficient for the variable that we want to solve is in negative. For Inequality, moving the negative coefficient for the variable to another side will force the Inequality sign to swap to opposite.

$x < \frac{ - 7}{ - 1} \\ x < 7$
