What is the value of x in the equation −x = 4 − 3x + 6? A. 5 B. 10 C. −5 D. −10

Ann [662]

$-x = 4-3x+6$

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 :

$\frac{2x}{2} = \frac{10}{5}$

$x = 5$

Answer a

hope this helps!
