Answer 2

Let's solve each of these equations step by step:

1. 3 7/24 + х = 5

First, subtract 3 7/24 from both sides to isolate the variable x:

х = 5 - 3 7/24

Now, convert 3 7/24 to an improper fraction:

3 7/24 = (3*24 + 7)/24 = (72 + 7)/24 = 79/24

So, the equation becomes:

x = 5 - 79/24

To subtract fractions, you need a common denominator, which is 24 in this case:

x = (120/24) - (79/24)

Now, subtract the fractions:

x = (120 - 79)/24

x = 41/24

2. х + 0.52 = 1

Subtract 0.52 from both sides to isolate the variable x:

x = 1 - 0.52

x = 0.48

3. (234 + х) - 456 = 178

First, simplify the equation by combining like terms on the left side:

234 + х - 456 = 178

Now, add 456 to both sides to isolate the variable x:

х - 456 = 178 + 456

х - 456 = 634

Finally, add 456 to both sides to solve for x:

х = 634 + 456

х = 1090

So, the solutions to the equations are:

1. x = 41/24
2. x = 0.48
3. x = 1090
