70-30=10+_
70 - 30 = 40
40 - 10 = ?
30
40 - 10 = 30
To solve the equation 70-30=10+_, you need to find the value for the blank space. To do this, follow these steps:
1. Start by subtracting 30 from 70 on the left side of the equation: 70 - 30 = 40.
2. Now, we have the equation 40 = 10 + _.
3. To find the value of the blank space, you need to subtract 10 from 40. Subtracting 10 from both sides of the equation will keep it balanced: 40 - 10 = 30.
4. Therefore, the value of the blank space is 30.
