Question

1. find the missing number that makes the equation true.

$24 + \underline{\quad} = 7 + 15 + 8$
$46 - 5 = 10 + 10 + \underline{\quad}$

Explanation:

Step1: Calculate right-hand side (RHS) of first equation

First compute $15+8=23$, then $7+23=30$.
So $7+15+8=30$

Step2: Solve for missing number in first equation

Let missing number be $x$. $24+x=30$, so $x=30-24=6$.

Step3: Calculate left-hand side (LHS) of second equation

$46-5=41$

Step4: Solve for missing number in second equation

Let missing number be $y$. $10+10+y=41$, so $20+y=41$, $y=41-20=21$.

Answer:

First missing number: $6$
Second missing number: $21$
