Solving multi-step problems using linear equations in one variable

What are Infinitely Many Solution equations?

• This equation is true for any x value you place. This equation is also called identities.

• Equations does not have any possible x value to make it true.

• Equations are equations that has only one solution. There are no other solutions that you can enter into that equation to make it true.

Solve if possible:

3r - 5 = 2r

• No solution

• Infinitely many solutions

• r = 5

Answer explanation

The given question is a simple algebra equation. To find the value of 'r', the equation 3r - 5 = 2r must be solved. By subtracting 2r from both sides, we get r - 5 = 0. Adding 5 to both sides, we find that r equals 5, thus confirming the correct option 'r = 5'.
