Question

(700:x+20):4=40 срочно

Answer 1

$700 \div x + 20 = 40 \times 4 = 160 \\ 700 \div x = 160 - 20 = 140 \\ x = 700 \div 140 \\ x = 5$

Answer 2

To solve this equation, you need to isolate the variable x. Here's how:

1. Multiply both sides by 4 to get rid of the fraction:

   (700:x+20) * 4 = 40 * 4

2. Simplify the right-hand side:

   700:x + 20 = 160

3. Subtract 20 from both sides:

   700:x = 140

4. Multiply both sides by x to isolate x:

   700 = 140x

5. Divide both sides by 140:

   x = 5

Therefore, the solution to the equation (700:x+20):4=40 is x=5.
