1. Problem Description

The problem asks us to find the missing numbers in two equations:

1. $150 + ? = 500$

2. $172 - ? = 60$

2. Solution Steps

For the first equation, $150 + ? = 500$, we need to find the number that, when added to 150, equals

5

0

0. We can find this by subtracting 150 from

5

0

0.

$500 - 150 = 350$

For the second equation, $172 - ? = 60$, we need to find the number that, when subtracted from 172, equals

6

0. We can find this by subtracting 60 from

1

7

2.

$172 - 60 = 112$

3. Final Answer

The missing numbers are 350 and

1

1

2. Therefore:

1. $150 + 350 = 500$

2. $172 - 112 = 60$
