Question

How do you solve `-2x+8>3x+10`?

Answer 1

x <`- 2 /5`

Explanation:

Inequations are solved in a similar way to solving equations.

( collect terms with x to one side usually the left and numbers to the other )

so : - 2x - 3x > 10 - 8 hence - 5x > 2

(To solve for x divide both sides by (- 5 ) . Here you must reverse the inequality sign as dividing by a negative quantity- do the same if multiplying by a negative.)

`rArr( -5x)/-5 < 2/-5 rArr x < - 2/5`

Example : -1 < 2

multiply both sides by ( - 1 ) : gives 1 < - 2 which is clearly incorrect and hence the need to reverse the inequality sign .
