Question

В3*1а=а31 пожалуйста помогите

Answer 1

3 умножаем на такое число чтобы в произведении стояла еденица на месте разряда едениц: 3*7=21 следовательно а=7, получаем б3*17=731, из 731 вычитаем то что известно, а это 3*17 получаем 731-51=680, 680:17=40, т.е. 4 десятка, значит ответ 43*17=731

Answer 2

Equation Solution

To solve the equation 3*1a = a31, we can follow these steps:

1. First, let's subtract a from both sides of the equation to isolate the constant term on one side. 2. Then, we can factor out the common term on the left-hand side.

Following these steps, the solution is as follows:

3*1a - a = a31 - a
2a = a31 - a
2a = 31
a = 31/2

So, a = 31/2.

This solution is derived from the equation 3*1a = a31, and the steps taken are based on standard algebraic principles.
