n=4
3n+6=18 n+2=6 n=4
3n+18 is an algebraic expression and n is an unknown variable
3n + 3(6 + 7n) = 3n + 18 + 21n = 24n + 18
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
8 + 3(6) = 8 + 18 = 26
3n+18 !
3n + 6 = n + 202n = 14n = 7
3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3
s = 9n - 18.
How do you find the answer to this equation: 3n equals 18
The expression equivalent to ( 3(n + 6) ) is ( 3n + 18 ). This is obtained by distributing the 3 to both terms inside the parentheses: ( 3 \times n + 3 \times 6 ). Thus, the simplified expression is ( 3n + 18 ).
It is the same as 6 + 18n = 6*(1 + 3n).
