We need to solve the equation:


-4\left(x\right)=-3\left(-x+1\right)-4

We can start by expanding the products:


\begin{gathered} -4x=-3(-x)-3(1)-4 \\ \\ -4x=3x-3-4 \\ \\ -4x=3x-7 \end{gathered}

Now, we can apply the same operations on both sides of the equation until we isolate the variable x and find its value:


\begin{gathered} -4x-3x=3x-7-3x \\ \\ -7x=-7 \\ \\ (-7)/(-7)x=(-7)/(-7) \\ \\ x=1 \end{gathered}

Answer: x = 1
