How do you find the answer to this equation: 3n equals 18
8 + 3(6) = 8 + 18 = 26
s = 9n - 18.
3n+18 is an algebraic expression and n is an unknown variable
3n + 4n = 42 7n = 42 n = 42/7 n = 6
How do you find the answer to this equation: 3n equals 18
8 + 3(6) = 8 + 18 = 26
3n + 6 = n + 202n = 14n = 7
s = 9n - 18.
3n+18 is an algebraic expression and n is an unknown variable
n=4
n=6
3n + 3(6 + 7n) = 3n + 18 + 21n = 24n + 18
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
n = -6
22n + 2.
n=1/3 or 0.333333333333333 repeated.
