Question

What value of x makes the equation true? 6 6x + 8 = 3x - 19 : A. X=-9 B. -- 3 C. = -3 D. x= 3​

Answer 1

Answer:

A. x = -9

Step-by-step explanation:

6x + 8 = 3x - 19 <== subtract 3x from both sides

-3x       -3x

3x + 8 = -19 <== subtract 8 from both sides

    - 8     - 8

3x = -27 <== divide both sides by 3

/3     /3

x = -9

Hope this helps!

Answer 2

Answer:

$\tt x=-9$

Step-by-step explanation:

$\tt 6x + 8 = 3x - 19$

Subtract 8 from both sides:-

$\tt 6x+8-8=3x-19-8$

$\tt 6x=3x-27$

Subtract 3x from both sides:-

$\tt 6x-3x=3x-27-3x$

$\tt 3x=-27$

Divide both sides by 3:-

$\tt \cfrac{3x}{3}=\cfrac{-27}{3}$

$\tt x=-9$

The vaule of x that makes the equation true is A) x= -9.
