Answer:
n = 9
Step-by-step explanation:
5(n-3) = 30
Expand the brackets. (Multiply n by 5 then multiply -3 by 5.)
5n-15 = 30
Isolate 5n.
5n = 30+15
Evaluate.
5n = 45
Find n.
n = 45 ÷ 5
n = 9
Answer:
n = 9
Step-by-step explanation:
1) divide both sides by 5 to cancel it out
(n-3=6)
2) add 3 to each side to cancel out the -3
(n=9)
You could factor the 5 to get 5n-15=30 but dividing by 5 just makes the number easier
