Question

3100*20+x=62000+700 x+300=31*300

Answer 1

3100*20+х=62000+700

3100*20+х=62700

62000+х=62700

х=62700-62000

х=700

х+300=31*300

х+300=9300

х=9300-300

х=9000

Answer 2

Let's solve the equation step by step:

Given equation 1: 3100 * 20 + x = 62000 + 700x + 300

Given equation 2: 300 = 31 * 300

First, simplify equation 2: 300 = 9300

Since equation 2 is not possible (it's contradictory), there seems to be an error. It's possible that you made a mistake when typing the equation. If you could provide the correct equations, I'd be happy to help you solve them.
