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: \[ x = 37 \]
