Step 2: To solve for , add 5 to both sides of the equation to get:
Which simplifies to:
Step 3: To verify, substitute 46 back into the context of the problem:
Subtract 5 from 46, which gives us:
This confirms our solution is consistent with the problem statement.
Therefore, the solution to the problem is .
a is negative number.
b is negative number.
What is the sum of a+b?
Great question! You add 5 because you need to undo the subtraction. Think of it like this: if x - 5 = 41, then x = 41 + 5. Addition and subtraction are opposite operations.
Look at what's being done to the variable. If it's x - 5, add 5 to both sides. If it's x + 5, subtract 5 from both sides. Always use the opposite operation!
Yes! You can think: "What number minus 5 equals 41?" Then work backwards: 41 + 5 = 46. Both methods give the same answer!
Remember: whatever you do to one side, you must do to the other side. This keeps the equation balanced like a scale. If you add 5 to the left side, add 5 to the right side too.
Substitute your answer back into the original word problem. Ask yourself: "Does 46 - 5 really equal 41?" If yes, you're right! If no, check your work.
