how do u solve 8-3r=2r+2

Question

solve for r

Answer 1

8 - 3r = 2r + 2

 

Add 3r to both sides of the equation:

8 - 3r + 3r = 2r + 2 + 3r

8 = 5r + 2

Subtract 2 from both sides of the equation:

8 - 2 = 5r + 2 - 2

6 = 5r

Now divide both sides of the equation to find the value of r:

6/5 = 5r/5

r = 6/5

 

So the solution is r = 6/5
