1,5•1,6+х+0,6=40

To solve the equation \(1.5 \cdot 1.6 + x + 0.6 = 40\), first calculate \(1.5 \cdot 1.6\):

\[ 1.5 \cdot 1.6 = 2.4 \]

Now, the equation becomes:

\[ 2.4 + x + 0.6 = 40 \]

Next, combine the constants on the left side:

\[ 2.4 + 0.6 = 3.0 \]

So, the equation simplifies to:

\[ 3.0 + x = 40 \]

Now, isolate \(x\) by subtracting 3.0 from both sides:

\[ x = 40 - 3.0 \] \[ x = 37.0 \]

Therefore, the solution is:

\[ x = 37 \]
