Question

18y-7y-10=12; 11y=12+10; 11y=22; y=22:11; y=2

Answer 1

18y-7y-10=12              
11у-10=12
11у=12+10
11у=22
у=11:22
у=2

Answer 2

11у= 22 , у=2; ты же сама уже все решила)

Answer 3

Your calculations are almost correct, but there is a minor mistake in your final step. Let's go through it again:

Starting with your equation:

18y - 7y - 10 = 12

Combine like terms:

(18y - 7y) - 10 = 12

11y - 10 = 12

Now, add 10 to both sides of the equation to isolate 11y:

11y - 10 + 10 = 12 + 10

11y = 22

Now, divide both sides by 11 to solve for y:

(11y)/11 = 22/11

y = 2

So, the correct value of y is indeed 2.
