Question

What is the value of x in the equation −x = 4 − 3x + 6?

A. 5
B. 10
C. −5
D. −10

Answer 1

`-x = 4 - 3x + 6 \\ \\ -x = -3x + 10 \\ \\ -x + 3x = 10 \\ \\ 2x = 10 \\ \\ x = (10)/(2) \\ \\ x = 5 \\ \\`

The answer is: x = 5.

Answer 2

`-x = 4-3x+6`

Refine
`4-3x + 6`


`-3x = 4+6`


`-3x = 10`

Add
`3x` to both sides:


`-x + 3x = -3x + 10 + 3x`


`2x = 10`

Divide both sides by 2 :


`(2x)/(2) = (10)/(5)`


`x = 5`

Answer a
