These written problem can be difficult to understand. But once we get all the words and their meanings then it comes together. The word "is" usually means equal. Here's how this will look.
5(2x-8)=-10 Multiply out will give us:
10x-40=-10 Add 40 to both sides will be:
10x=30 Divide both sides by 10 will be:
x=3 Enter this into the equation and it works out.
