Question

what is the second step in solving for n in the equation 5.6 (n + 1.42) = 7.8? (1 point)
subtract 1.42 from both sides.
divide both sides by 5.6.
subtract 5.6 from both sides.
add 1.42 to both sides.

Explanation:

Step1: Isolate the term with n

To solve the equation \(5.6(n + 1.42)=7.8\), the first - step is to get rid of the coefficient 5.6 that is multiplying the parentheses. We do this by dividing both sides of the equation by 5.6. So we have \(\frac{5.6(n + 1.42)}{5.6}=\frac{7.8}{5.6}\), which simplifies to \(n + 1.42=\frac{7.8}{5.6}\).

Step2: Solve for n

After getting \(n + 1.42=\frac{7.8}{5.6}\), to isolate \(n\), we subtract 1.42 from both sides of the equation.

Answer:

Subtract 1.42 from both sides.
