solve this one step by please : q-r=r, for r
q-r=r
Subtract q to both sides of the equation.
-r = r + q
q-r=r
q-r=q-q
r/r=r-q/r
r=r-q
To solve the equation q - r = r for r, we need to isolate the variable r on one side of the equation.
Here's how to do it in one step:
Step 1: Add r to both sides of the equation.
q - r + r = r + r
Simplifying the left side, we get:
q = 2r
Now, to solve for r, we need to isolate it.
Step 2: Divide both sides of the equation by 2.
q/2 = r
And that's it! We have solved the equation q - r = r for r, and the solution is r = q/2.
