Answer: 3
Step-by-step explanation: When you solve for x you get 2 so when you put that into the equation (2+1) you get 3. You solve for x but solving this equation (x+5) = (x+1) Hope this helps :)
Answer:
r= -5/3
Step-by-step explanation:
:Simplify both sides of the equation.
2+3r+3=0
(3r)+(2+3)=0(Combine Like Terms)
3r+5=0
3r+5=0
Step 2: Subtract 5 from both sides.
3r+5−5=0−5
3r=−5
Step 3: Divide both sides by 3.
3r
