1000+38x=900+40=

To solve the equation \(1000 + 38x = 900 + 40\), we can simplify the right side first:

\[ 900 + 40 = 940 \]

Now, the equation becomes:

\[ 1000 + 38x = 940 \]

Next, we subtract 1000 from both sides:

\[ 38x = 940 - 1000 \] \[ 38x = -60 \]

Now, we divide both sides by 38 to solve for \(x\):

\[ x = \frac{-60}{38} \]

We can simplify the fraction:

\[ x = \frac{-30}{19} \]

Thus, the solution is:

\[ x = -\frac{30}{19} \]

This is the final answer.
