Hi there!
<h2>n = 2.5</h2>
-5(4n - 2.4) + 2(1.3 + 6n) = -5.4
Distribute the coefficients outside of the parenthesis:
-5(4n) - 5(-2.4) + 2(1.3) + 2(6n) = -5.4
-20n + 12 + 2.6 + 12n = -5.4
Combine like terms:
-8n + 14.6 = -5.4
Subtract 14.6 from both sides:
-8n = -20
Divide both sides by -8:
-8n/(-8) = -20/(-8)
n = 2.5
Answer:
n = 2.5
Step-by-step explanation:
distribute
-20n + 12 + 2.6 + 12n = -5.4
combine terms
-8n + 14.6 = -5.4
subtract 14.6 from both sides
-8n = -20
divide by -8
n = 2.5
