Question

What’s value of x in 12x-11=2x+5

Answer 1

x = 1.6 or
`(8)/(5)`

Explanation:

12x - 11 = 2x + 5

Add 11 to both sides,

12x - 11 + 11 = 2x + 5 + 11

12x = 2x + 16

Subtract 2x from both sides,

12x -2x = 2x - 2x + 16

10x = 16

Divide both sides by the same factor (in this cas the factor is 10),

`(10x)/(10) =(16)/(10)`

`x=(8)/(5)`

x = 1.6 or
`(8)/(5)`
