Question

75 = 3 (-6n- 5) what is the answer

Answer 1

Reorder the terms: 75 = 3(-5 + -6n) 75 = (-5 * 3 + -6n * 3) 75 = (-15 + -18n) Solving 75 = -15 + -18n Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '18n' to each side of the equation. 75 + 18n = -15 + -18n + 18n Combine like terms: -18n + 18n = 0 75 + 18n = -15 + 0 75 + 18n = -15 Add '-75' to each side of the equation. 75 + -75 + 18n = -15 + -75 Combine like terms: 75 + -75 = 0 0 + 18n = -15 + -75 18n = -15 + -75 Combine like terms: -15 + -75 = -90 18n = -90 Divide each side by '18'. n = -5 Simplifying n = -5

Hope that helps

Answer 2

75=3(-6n-5)
divide both sides by 3:
25=-6n-5
Add five to both sides:
30=-6n
Divide both sides by -6:
-5=n

Hope this helps :)
