Let's give it a go:3n - 6 = 9Add 6 to each side of the equation:3n = 15Divide each side by 3:n = 5
3n + 6 = n + 202n = 14n = 7
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
Let n be the number, then: 1/n - 1/3n = 1/6 Solve the subtraction on the left: 1/n - 1/3n = 3/3n - 1/3n = 2/3n But we know this is 1/6, thus: 2/3n = 1/6 ⇒ 3n = 12 ⇒ n = 4 Thus the number is 4.
73n-6+6=15+63n=213n/3=21/3n=7
6=3n or 3n=6
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
3n+6=18 n+2=6 n=4
Let's give it a go:3n - 6 = 9Add 6 to each side of the equation:3n = 15Divide each side by 3:n = 5
3n + 6 = n + 202n = 14n = 7
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
Assume the expression is: 15 = 9 + 3n Subtract both sides by 9 to get: 15 - 9 = 9 - 9 + 3n 6 = 3n Finally, divide both sides by 3 to get: 6/3 = 3n/3 n = 2
Let n be the number, then: 1/n - 1/3n = 1/6 Solve the subtraction on the left: 1/n - 1/3n = 3/3n - 1/3n = 2/3n But we know this is 1/6, thus: 2/3n = 1/6 ⇒ 3n = 12 ⇒ n = 4 Thus the number is 4.
73n-6+6=15+63n=213n/3=21/3n=7
How do you find the answer to this equation: 3n equals 18
Yes when multiplying. No when adding. 3n^3 + 3n^3 = 6n^3 3n^3 x 3n^3 = 9n^6
3n + 6 = 39Therefore 3n = 39 - 6 = 33n = 33 / 3Therefore, n = 11
