+2446 \(?=63\)
This is your original equation. I'll replace your question mark with an x instead:
\(23-46=40-x\)
Now, solve by isolating x:
| \(23-46=40-x\) | Simplify the left hand side of the equation |
| \(-23=40-x\) | Subtract 40 on both sides |
| \(-63=-x\) | Multiply by -1 on both sides |
| \(x=63\) | |
x=63 is your final answer.
