Answer:

x = -17

Step-by-step explanation:

The equation is:


\sf{-5x-5=-4x+12}

First, add 4x on each side:


\sf{-5x+4x-5=12}


\sf{-x-5=12}

Add 5 to each side


\sf{-x=12+5}


\sf{-x=17}


\sf{x=-17}

Hence, x = -17.

Answer:

x = -17

Step-by-step explanation:

-5x - 5 = -4x + 12 we want to isolate the variable so add 5x to both sides.

-5x + 5x - 5 = -4x + 5x + 12

-5 = x + 12 Subtract 12 from both sides

-5 - 12 = x

-17 = x
