Question

0.4(2-) 0.2(9 + 7) A)-3 B - 1 C) 3 D) all real numbers

Answer 1

Let us solve the equation to arrange the steps

`-3(4+3x)+5x=-16`

In the first step, we must multiply the bracket by -3 (distributive property)

`(-3)(4)_{}+(-3)(3x)=-12-9x`

Then the equation is

`-12-9x+5x=-16`

Now add the like terms on the left side

`\begin{gathered} -12+(-9x+5x)=-16 \\ -12x+(-4x)=-16 \\ -12-4x=-16 \end{gathered}`

Next step, add 12 to both sides
