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
