Solve the equation
To solve the given equation , we'll follow these steps:
Now, let's work through each step:
Step 1: Subtract 5.5 from both sides.
We have:
This simplifies to:
Step 2: Divide both sides by 7 to solve for .
So, we divide by 7:
This simplifies to:
Therefore, the solution to the problem is .
Solve for X:
\( x - 3 + 5 = 8 - 2 \)
Subtracting constants first isolates the variable term (7x), making division cleaner. If you divide first, you get messy fractions that are harder to work with!
Adding 5.5 would give you , leading to the wrong answer. Remember: to eliminate a positive constant, you must subtract it from both sides.
Follow the reverse order of operations! Since addition/subtraction come last in PEMDAS, undo them first. Then handle multiplication/division.
Yes! You can also work backwards: if x = 2, then 7(2) = 14, and 14 + 5.5 = 19.5. This confirms your solution is correct!
That's completely normal! Linear equations often have decimal or fractional solutions. Just make sure to substitute back and verify your answer.
