9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
3x plus 9 equals what?
the answer is -3x = 0
28
If 5 x equals 9 plus 2x then x equals?
9 - 5n
6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
5n - 9 = 2n + 6 : Add 9 to both sides 5n = 2n + 15 : Subtract 2n from both sides 3n = 15 : Divide both sides by 3 n = 5
-5n+9=-46 -5n+9-9=-46-9 -5n=-55 -5n/-5=-55/-5 n=11
I'm assuming you are solving for n.2n + 6 = 7n - 9 {add nine to each side}2n + 15 = 7n { subtract 2n from each side}15 = 5n {divide each side by 5}3 = n
Subtract 2n from each side: 3n - 9 = 6 Add 9 to each side: 3n = 15 Divide both sides by 3: n = 5 Therefore, n = 5
9+2n=5n this is how you would set up the problem 9+2n-2n=5n-2n then you subtract the number with the variable on each side 9=3n this is what it leaves you with 9/3=3n/3 then you divide three by both sides to get the variable by itself 3=n then you have your answer Hope this helps you!!
9 - 5n + 1 = 15 -5n = 15 - 10 n = -5/5 n = -1
3 + 3n = 9 + 2n + 4n n = -2
-3
9-5n+1 = 15 -5n = 15-9-1 -5n = 5 Divide both sides of the equation by -5 to find the value of n: n = -5
