Solve
h=30r+20
there is nothing to be solved. h equals 30r plus 20.
To solve the equation h = 30r + 20, you need to isolate the variable r on one side of the equation.
Step 1: Start with the given equation h = 30r + 20.
Step 2: Subtract 20 from both sides of the equation to get rid of the constant term:
h - 20 = 30r.
Step 3: Divide both sides of the equation by 30 to isolate r:
(h - 20) / 30 = r.
So the solution to the equation h = 30r + 20 is r = (h - 20) / 30.
