Question

0.25r-0.125+0.5r=0.5+r solve the equation?

Answer 1

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!
