How much is X worth?
To solve the equation , we'll follow these steps:
Hence, the value of is .
\( x+7=14 \)
\( x=\text{?} \)
You need to isolate the term with x first! Think of it like unwrapping a gift - you remove the outer layer (the constant +10) before getting to the inner layer (the coefficient 9).
That's completely normal! If the constant on the left is larger than the number on the right, you'll get a negative result. Just continue with the steps - negative numbers follow the same rules.
Follow the reverse order of operations! Since addition/subtraction come after multiplication/division in PEMDAS, you undo them first when solving equations.
Yes! You can also think about it logically: "What number times 9, plus 10, equals 91?" Try different values until you find one that works, then verify with substitution.
The same steps work! You might end up with fractions or decimals, but the process is identical: subtract constants first, then divide by the coefficient.
