Question

55×х=820-710 300-×=42×2

Answer 1

55х=110
х=110:55
х=2
300-х=84
х=300-84
х=216

Answer 2

Let's solve these equations step by step:

1. 55×х = 820 - 710

To find the value of 'x' in this equation, we need to isolate 'x' on one side of the equation.

Step 1: Subtract 820 - 710 on the right side: 55×х = 110

Step 2: Divide both sides by 55 to solve for 'x': x = 110 / 55 x = 2

So the value of 'x' is 2.

2. 300 - × = 42 × 2

In this equation, we need to find the value of the missing number represented by '×'.

Step 1: Calculate 42 × 2: 42 × 2 = 84

Step 2: Subtract 84 from 300 on the left side of the equation: 300 - × = 84

Step 3: To find the value of '×', subtract 84 from 300: × = 300 - 84 × = 216

So the missing number (×) is 216.
