Answer:
- Algebraic equation: 2x - 20 = 5
- Solved: x = 12.5
Explanation:
Let x be the number
To write the algebraic expression:
- "Twenty less" means subtraction.
- "Two times a number" means multiplication.
- The answer to the equation: 20
- Put them together with the numbers: 2x - 20 = 5
To solve:
- Write it out: 2x - 20 = 5
- Add 20 to each side, so it now looks like this: 2x = 25
- Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 12.5
