№6 345008-269871,126547-79652,182*3,247*4,208*4,109*8. №8 х+320=8087 Х-180=240:3 400-Х=275+25

Answer 1

6)  345008-269871=75137
     126547-79652=46895
     182×3=546       247×4=988       208×4=832      109×8=872

8)  х+320=8087                   х-180=240:3                      400-х=275+25
     х=8087-320                     х-180=80                           400-х=300
     х=7767                             х=80+180                          х=400-300
    7767+320=8087                х=260                               х=100
           8087=8087              260-180=240:3                   400-100=275+25
                                                   80=80                                300=300

Answer 2

It looks like you've provided a series of equations and expressions. Let's break them down one by one:

1. 345008 - 269871 This is a subtraction operation: 345008 - 269871 = 75137

2. 126547 - 79652 Another subtraction operation: 126547 - 79652 = 46895

3. 182 * 3 A multiplication operation: 182 * 3 = 546

4. 247 * 4 Another multiplication operation: 247 * 4 = 988

5. 208 * 4 One more multiplication operation: 208 * 4 = 832

6. 109 * 8 Yet another multiplication operation: 109 * 8 = 872

Now, let's look at the equations:

7. x + 320 = 8087 This is a linear equation. To solve for 'x,' you need to isolate 'x' on one side of the equation: Subtract 320 from both sides: x = 8087 - 320 x = 7767

8. x - 180 = 240 / 3 This is another linear equation. To solve for 'x,' isolate 'x' on one side of the equation: Add 180 to both sides: x = 240 / 3 + 180 x = 80 + 180 x = 260

9. 400 - x = 275 + 25 Again, a linear equation. To solve for 'x,' isolate 'x' on one side of the equation: Subtract 25 from both sides: 400 - x = 275 + 25 - 25 400 - x = 300 Now, subtract 400 from both sides: -x = 300 - 400 -x = -100 Finally, multiply both sides by -1 to solve for 'x': x = 100

So, the solutions to the equations are:

• x = 7767
• x = 260
• x = 100
