To solve the equation , we aim to find the value of by isolating it on one side.
Therefore, we have found that the solution to the equation is , which matches the given answer choice 2.
7
\( x+7=14 \)
\( x=\text{?} \)
Because 7 is being added to x, we need the opposite operation (subtraction) to cancel it out. Think of it as undoing what was done to x!
Isolating x means getting x completely by itself on one side of the equation. You want something, not something.
Look at what's happening to x and do the opposite. If something is added (+7), subtract it. If something is subtracted, add it back.
Yes! Whatever you do to one side, you must do to the other side. This keeps the equation balanced like a scale.
Negative answers are completely normal in algebra! Just make sure to check your work by substituting back into the original equation.
You can also think: "What number plus 7 equals 14?" Since 7 + 7 = 14, the answer must be 7. This mental check confirms our algebraic work!
