Question

M-4m=45 84= 2y-0,5 9 108 4,5

Answer 1

M-4m=45
-3m=45
m=-9

84=2у-0,5
-2у=84,5
у=-42,25

Answer 2

To solve the equations, we need to find the values of variables 'm' and 'y'. Let's tackle each equation one by one:

1. M - 4m = 45

First, combine the 'm' terms on the left side:

M - 4m = M - 4m

Now, since there are no other terms on the right side, we can equate the coefficients of 'm' on both sides:

1 = -4

This equation is not possible as there is no value of 'm' that would satisfy it. It seems like there might be an error or misunderstanding in the equation.

2. 84 = 2y - 0.5

Add 0.5 to both sides to isolate the '2y' term:

84 + 0.5 = 2y - 0.5 + 0.5

84.5 = 2y

Now, to solve for 'y', divide both sides by 2:

y = 84.5 / 2 y = 42.25

So, the value of 'y' is 42.25.

3. 9 108 4.5

This equation seems to be incomplete or unclear. It's not a proper mathematical expression or equation. If you could provide more context or clarify this equation, I'd be happy to help you solve it.

In summary:

• The first equation doesn't seem to be valid.
• The value of 'y' in the second equation is 42.25.
• The third equation is incomplete or unclear.
