Question

247-(y+83)=112. 248-(y+123)=24. 478-(256+×)=143. 375-(×-218)=123. 659-(345-×)=427

Answer 1

1.) 247-(у+83)=112
247-у-83=112
164-у=112
-у=112-164
-у=-52
у=-52÷(-1)
у= 52

2.) 248-(у+123)=24
248-у-123=24
125-у=24
-у=24-125
-у=-101
у=101

3.) 478-(256+х)=143
478-256-×=143
222-х=143
-х=143-222
-х=-79
х=79

4.) 375-(Х-218)=123
375-х+218=123
593-х=123
-х=123-593
-х=-470
х=470

5.) 659-(345-х)=427
659-345+х=427
314+х=427
х=427-314
х=113

Answer 2

To solve these equations for "x" and "y," we'll go through each one step by step:

1. 247 - (y + 83) = 112

Let's start by simplifying the equation by adding 83 to both sides:

247 - (y + 83) + 83 = 112 + 83

This simplifies to:

247 - y = 195

Now, isolate "y" by subtracting 247 from both sides:

• y = 195 - 247
• y = -52

So, the solution for y is -52.

2. 248 - (y + 123) = 24

Let's simplify the equation by adding 123 to both sides:

248 - (y + 123) + 123 = 24 + 123

This simplifies to:

248 - y = 147

Now, isolate "y" by subtracting 248 from both sides:

• y = 147 - 248
• y = -101

So, the solution for y is -101.

3. 478 - (256 + x) = 143

Let's simplify the equation by adding 256 to both sides:

478 - (256 + x) + 256 = 143 + 256

This simplifies to:

478 - x = 399

Now, isolate "x" by subtracting 478 from both sides:

• x = 399 - 478
• x = -79

So, the solution for x is -79.

4. 375 - (x - 218) = 123

Let's simplify the equation by adding 218 to both sides:

375 - (x - 218) + 218 = 123 + 218

This simplifies to:

375 + 218 - x = 341

Now, isolate "x" by subtracting 593 from both sides:

• x = 341 - 593
• x = -252

So, the solution for x is -252.

5. 659 - (345 - x) = 427

Let's simplify the equation by subtracting 345 from both sides:

659 - (345 - x) - 345 = 427 - 345

This simplifies to:

659 - 345 + x = 82

Now, isolate "x" by subtracting 314 from both sides:

x = 82 - 314 x = -232

So, the solution for x is -232.

To summarize:

• The solution for y in the first equation is y = -52.
• The solution for y in the second equation is y = -101.
• The solution for x in the third equation is x = -79.
• The solution for x in the fourth equation is x = -252.
• The solution for x in the fifth equation is x = -232.
