Question

Three added to eight times a number is the same as three times the value of two times the number -1

Answer 1

The number x is -3

Therefore x=-3

Explanation:

Given problem is "Three added to eight times a number is the same as three times the value of two times the number -1"

Let x be the number

It can be written as

`3+8* x=3(2* x-1)`

`3+8x=3(2x-1)` ( applying the distributive property )

`3+8x=3(2x)+3(-1)`

`3+8x=6x-3`

subtracting (6x-3) on both sides we get

`3+8x-(6x-3)=6x-3-(6x-3)`

`3+8x-6x+3=6x-3-6x+3`

`6+2x=0` ( ading the like terms )

`2x=-6`

`x=-(6)/(2)`

Therefore x=-3

The number x is -3
