Question

4249:7=х-79. 7008:8=х:2 1881:9=х+12,3216:8=х•6

Answer 1

Ответ:

4249:7=х-79

х-79=4249:7

х-79=607

х=607+79

х=686

7008:8=х:2

х:2=7007:8

х:2=876

х=876×2

х=1752

1881:9=х+12

х+12=1881:9

х+12=209

х=209-12

х=197

3216:8=х×6

х×6=3216:8

х×6=402

х=402:6

х=67

Answer 2

Let's solve each equation step by step:

1. 4249:7 = x - 79

To solve for x, we can first simplify the left side of the equation:

4249 ÷ 7 = 607

Now we have:

607 = x - 79

To isolate x, we can add 79 to both sides of the equation:

607 + 79 = x 686 = x

Therefore, x = 686.

2. 7008:8 = x:2

We can simplify the left side of the equation:

7008 ÷ 8 = 876

Now we have:

876 = x ÷ 2

To isolate x, we can multiply both sides of the equation by 2:

876 * 2 = x 1752 = x

Therefore, x = 1752.

3. 1881:9 = x + 12

Simplifying the left side of the equation:

1881 ÷ 9 = 209

Now we have:

209 = x + 12

To isolate x, we can subtract 12 from both sides of the equation:

209 - 12 = x 197 = x

Therefore, x = 197.

4. 3216:8 = x * 6

Simplifying the left side of the equation:

3216 ÷ 8 = 402

Now we have:

402 = x * 6

To isolate x, we can divide both sides of the equation by 6:

402 ÷ 6 = x 67 = x

Therefore, x = 67.

To summarize the results:

• x = 686 (from the first equation)
• x = 1752 (from the second equation)
• x = 197 (from the third equation)
• x = 67 (from the fourth equation)
