Answer:

To find the missing "?", we need to equate the two sides of the equation.

Starting with the left side:

5a + 10 - 3a + ? = 4a + 10

Expanding the expression on the left side:

5a + 10 - 3a + ? = 4a + 10

= 2a + 10 + ? = 4a + 10

Isolating the unknown "?":

2a + 10 + ? = 4a + 10

-2a -10 = -2a -10

? = 0

So the missing "?" is 0.

Hope this helps!
