The problem asks us to find the missing numbers in the following three equations: Equation 1: $? + 85 = 200$ Equation 2: $4 \times ? = 120$ Equation 3: $120 - 51 = ?$

1. Problem Description

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

Equation 1: $? + 85 = 200$

Equation 2: $4 \times ? = 120$

Equation 3: $120 - 51 = ?$

2. Solution Steps

Equation 1: $? + 85 = 200$

To find the missing number, we subtract 85 from

2

0

0. $200 - 85 = 115$

Therefore, the missing number is

1

1

5.

Equation 2: $4 \times ? = 120$

To find the missing number, we divide 120 by

4. $120 \div 4 = 30$

Therefore, the missing number is

3

0.

Equation 3: $120 - 51 = ?$

To find the missing number, we subtract 51 from

1

2

0. $120 - 51 = 69$

Therefore, the missing number is

6

9.

3. Final Answer

The missing numbers are:

Equation 1: 115

Equation 2: 30

Equation 3: 69
