Question

2X-5<9 solve inequality

Answer 1

Explanation:

2x<9+5

2x<14

2x/2<14/2

x<7

Answer 2

`\boxed {\boxed {\sf x <7}}`

Explanation:

To solve the inequality you must isolate the variable, which is x.

`2x-5 < 9`

5 is being subtracted from 2x. The inverse of subtraction is addition, so add 5 to both sides of the equation.

`2x-5+5 < 9+5`

`2x < 14`

x is being multiplied by 2. The inverse of multiplication is division, so divide both sides by 2.

`\frac {2x}{2} < \frac {14}{2}`

`x <7`

The solution to this inequality is x <7
