6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
3n = 618 n = 618 ÷ 3 n = 206
3n and n = 4? 3n ( the four replaces the n 3(4) = 12 =======
3n-11 = 19 3n = 19+11 3n = 30 Divide both sides of the equation by 3 to find the value of n: n = 10
n = 3 3n x 2 = 18 3n x 2 / 2 = 18 / 2 3n = 9 3n / 3 = 9 / 3 n = 3
