Question 635544: Solve the equation: 4-5(y+2)=2(y-1)-7y-4
I keep attempting to solve for y and I keep getting -2. When I checked my answer using the widget on this website, it said I should be getting 0. I don't understand the steps they're using.
I distributed the 4 and -5 to (y+2) and the 2 to (y-1). I combined the like terms on both sides of the equal sign, then I moved my y to the left and my constants to the right. What am I doing wrong?
