5.6 (n+1.42)=7.8

To solve this equation, we need to isolate the variable n.

To start, let's distribute the 5.6 to both terms within the parentheses:

5.6n + (5.6 * 1.42) = 7.8

Simplifying further:

5.6n + 7.952 = 7.8

Next, we want to isolate the variable n. We can do this by subtracting 7.952 from both sides of the equation:

5.6n = 7.8 - 7.952

Subtracting the two values:

5.6n = -0.152

To solve for n, we divide both sides of the equation by 5.6:

n = -0.152 / 5.6

Evaluating this division:

n ≈ -0.0271
