9-3r=14
9-3r=14
-3r = 14 - 9
-3r = 5
r = -5/3
r = =1 2/3
r = -1 2/3
To solve the equation 9 - 3r = 14, you need to isolate the variable 'r' by performing a series of steps.
Step 1: Start by subtracting 9 from both sides of the equation to move the constant term to one side:
9 - 3r - 9 = 14 - 9
-3r = 5
Step 2: Next, we want to isolate 'r', so we divide both sides of the equation by -3:
-3r / -3 = 5 / -3
r = -5/3
Therefore, the solution for the equation 9 - 3r = 14 is r = -5/3.
