Answer 3

Let's solve each equation step by step:

1. 30×(x×6) = 189720 To solve this equation, first, we can simplify the left side by performing the multiplication inside the parentheses:

30 × (x × 6) = 30 × 6x = 180x

Now, the equation becomes:

180x = 189720

To isolate x, we can divide both sides by 180:

x = 189720 / 180 x = 1054

So the solution for the first equation is x = 1054.

2. 3438 + x ÷ 6 = 10004 To solve this equation, first, we can isolate x by subtracting 3438 from both sides:

x ÷ 6 = 10004 - 3438 x ÷ 6 = 6566

Next, we can solve for x by multiplying both sides by 6:

x = 6566 × 6 x = 39396

So the solution for the second equation is x = 39396.

3. (800 - 180) ÷ x = 20 To solve this equation, first, we can simplify the left side by performing the subtraction inside the parentheses:

(800 - 180) ÷ x = 620 ÷ x

Now, the equation becomes:

620 ÷ x = 20

To isolate x, we can multiply both sides by x:

x × (620 ÷ x) = 20 × x

The x on the left side will cancel out:

620 = 20x

To find x, we can divide both sides by 20:

x = 620 / 20 x = 31

So the solution for the third equation is x = 31.

To summarize the solutions:

1. x = 1054
2. x = 39396
3. x = 31
