3-3r=4
Do you wish to solve for r?
Put r on one side and everything else on the other. First substract 3 from both sides.
3-3-3r = 4 - 3
combine.
-3r = 1
Multiply by -1
3r = -1
Divide both sides by 3
3r/3 = -1/3
r = -1/3
To solve the equation 3-3r=4 for r, you can follow these steps:
1. Start by isolating the variable r on one side of the equation. In this case, subtract 3 from both sides of the equation:
3 - 3 - 3r = 4 - 3
2. Simplify the equation by combining like terms:
-3r = 1
3. To further isolate the variable, multiply both sides of the equation by -1 (or divide by -1):
-1 * -3r = -1 * 1
4. Simplify the equation:
3r = -1
5. Finally, solve for r by dividing both sides of the equation by 3:
3r/3 = -1/3
6. Simplify the equation to get the final value of r:
r = -1/3
Therefore, the solution to the equation 3-3r=4 is r = -1/3.
