Question

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

x = −7
x = −13
x = 8
x = 2

Answer 1

D. x = 2 (last/fourth option)

Explanation:

`(x + 16)/(3) = 3x`

`x + 16 = 9x`

`x - 9x = - 16`

`- 8x = - 16`

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

Answer 2

(x + 16)/3 = 3x / · 3

x + 16 = 9x

x - 9x = 16

-8x = 16 / : (-8)

x = -2 ← the end
