Question

n/-3+5>4
plz help dont undrestand how to do this.

Answer 1

Step 1: Simplify n/-3

Step 2 :Rewrite the whole as a fraction using -3 as the denominator :

5 5 • -3
5 = — = ——————
1 -3


Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

n • -1 + 5 • 3 15 - n
———————— = ——————
3 3


Rewrite the whole as a fraction using 3 as the denominator :

4 4 • 3
4 = — = —————
1 3



Adding up the two equivalent fractions

(15-n) - (4 • 3) 3 - n
————————— = —————
3 3




Multiply both sides by 3 and Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

n-3 < 0

Add 3 to both sides

and the answer will be n < 3
