Question

Solve for x: the quantity of x plus 16 all over 3 = 3x

x = −7
x = −13
x = 8
x = 2

Answer 1

(x + 16)/3 = 3x / · 3

x + 16 = 9x

x - 9x = 16

-8x = 16 / : (-8)

x = -2 ← the end

Answer 2

Answer:

D. x = 2 (last/fourth option)

Step-by-step explanation:

$\frac{x + 16}{3} = 3x$

$x + 16 = 9x$

$x - 9x = - 16$

$- 8x = - 16$

$\boxed{\green{x = 2}}$
