Question

38 + x = 72x - 31 = 45x 4= 206 y = 18​

Answer 1

1) х=34
2) х=76
3) х=5
4) у=3

Answer 2

It seems like you've provided a set of equations and values, but they're not formatted in a clear way. Let me try to interpret and solve them.

We have the following equations and values:

1. $38 + x = 72x - 31$
2. $72x - 31 = 45x$
3. $4 = 206$
4. $y = 18$

Equation 3 ($4 = 206$) is not a valid equation, as $4$ is not equal to $206$. Equation 4 ($y = 18$) is a straightforward assignment.

Let's try to solve the first two equations for $x$:

From equation 1: $38 + x = 72x - 31$

Rearrange to solve for $x$: $38 + 31 = 72x - x$ $69 = 71x$ $x = \frac{69}{71}$

Now, let's solve equation 2 for $x$: $72x - 31 = 45x$

Rearrange to solve for $x$: $72x - 45x = 31$ $27x = 31$ $x = \frac{31}{27}$

These are the values of $x$ from the given equations. If you need further assistance or if there's a specific problem you'd like to solve, please provide more context or clarify the equations.
