Answer:
Step-by-step explanation:
Solve the equation r+3=2
r + 3 = 2
r = 2 - 3
r = -1
---------------
check
-1 + 3 = 2
2 = 2
the answer is good
Answer:
r = -1
Step-by-step explanation:
r + 3 = 2
Step 1 - Bring 3 to the other side of the equal sign:
r = 2 - 3
Step 2 - The 3 would turn into -3. Now subtract -3 from 2:
r = -1
Therefore, r is equal to -1.
r + 3 = 2
-1 + 3 = 2
2 = 2
The answer is correct when we put -1 into r.
