Answer 2

It looks like you have three equations involving variables x and y. Let's solve them one by one:

1. Equation 1: 3x = 0.81

To solve for x, divide both sides by 3: x = 0.81 / 3 x = 0.27

So, the solution for x is x = 0.27.

2. Equation 2: 23y - y = 6.6

Combine the y terms on the left side: 22y = 6.6

Now, isolate y by dividing both sides by 22: y = 6.6 / 22 y = 0.3

So, the solution for y is y = 0.3.

3. Equation 3: 5y - 2.54

It seems like there might be a typo in this equation. There is an equal sign missing. If the equation is written as 5y - 2.54 = 0, then we can solve for y:

Add 2.54 to both sides: 5y = 2.54

Now, isolate y by dividing both sides by 5: y = 2.54 / 5 y = 0.508

So, the solution for y is y = 0.508.

Please double-check the third equation to confirm if there is any missing information or a typographical error. If you provide the correct equation, I can help you solve it as well.
