The first step in solving for \( x \) in the equation \( 5.6(x + 1.42) = 7.8 \) is to divide both sides by 5.6. This simplifies the equation and isolates the expression involving \( x \).
Here is how it looks:
- Divide both sides by 5.6: \[ x + 1.42 = \frac{7.8}{5.6} \]
After that, you can proceed to subtract 1.42 from both sides to solve for \( x \).
