Answer 2

D) 4

Explanation:

To find the value of x that makes 3.2(3x - 7) = 16 true, we can use algebraic operations to rearrange the equation to isolate x.

Divide both sides of the equation by 3.2:

`\begin{aligned}(3.2(3x-7))/(3.2)&=(16)/(3.2)\\\\3x-7&=5\end{aligned}`

Add 7 to both sides of the equation:

`\begin{aligned}3x-7+7&=5+7\\\\3x&=12\end{aligned}`

Divide both sides of the equation by 3:

`\begin{aligned}(3x)/(3)&=(12)/(3)\\\\x&=4\end{aligned}`

Therefore, the value of x that makes the equation true is:

`\Large\boxed{\boxed{x=4}}`
