10 = 6 + e solve that

4

Step-by-step explanation:

10= 6 + 4

Carry over the 6 to the 10 and make e the subject on the right hand side of the equation as shown below:

10 - 6 = e

4= e

Therefore e is 4.

7.5

Step-by-step explanation:

Let's go through it together:

Since the two sides we are given are equal to 10, let's multiply.

10x10 = 100

If you were to do process of elimination, let's do 100x7.5

100x7.5 = 750.

Hope this helped!
