    You'll need to combine like terms. Anything attached to the variable of 'r' is one type of term, and everything without an 'r' is another. However, to start, let's get the r off of the right side. Subtraction is the inverse of addition, so we subtract the single r from both sides New equation: 0.25r-0.125r+0.5r-r=0.5 Now we can combine. We take the coefficients and add them 0.25-0.125+0.5-1=-3.75 So we have a coefficient of -3.75 New equation: -3.75r=0.5 But now we need to isolate r, or get it by itself on the left side. Division is the inverse of multiplication, so we shall divide both sides by -3.75 New equation: (In fraction form) r=(-2/15) And there you go!
