Question

Solve 3 (x+4) −5 = −1 (x−4) for x

Answer 1

x = -3/4

Explanation

`3(x+4)-5=-1(x-4)`

Distributing:

Adding x and subtracting 7 at both sides of the equation:

`\begin{gathered} 3x+7+x-7=-x+4+x-7 \\ 4x=-3 \end{gathered}`

Dividing by 4 at both sides of the equation:

`\begin{gathered} (4x)/(4)=-(3)/(4) \\ x=-(3)/(4) \end{gathered}`
