Answer 2

Ответ:

1) 9х+х=500

10х=500

х=500:10

х=50

2)6у +3у-у=6400

8у=6400

у=6400:8

у=800

Answer 3

Let's solve these equations step by step:

1. 9x + x = 500 Combining like terms on the left side: 10x = 500

Now, divide both sides by 10 to solve for x: 10x/10 = 500/10 x = 50

So, the solution to the first equation is x = 50.

2. 6y + 3y - y = 6400 Combining like terms on the left side: 6y + 3y - y = 8y

Now, the equation becomes: 8y = 6400

To solve for y, divide both sides by 8: 8y/8 = 6400/8 y = 800

So, the solution to the second equation is y = 800.
