x - 2 = 7 so x - 2 = 7 then convert that into an addition problem: 7 + 2 = x then add: 7 + 2 = 9 therefore x = 9

the sum of means (___+____) so you will need to open parentheses after the 2 times. 2*(7+x) is the expression you are looking for.

2, 3 and 7 are prime factors of 84. The prime factorization is 2 x 2 x 3 x 7.
2 x 7 x 7 = 98
A question of prime factors... The answer is 2 x 2 x 3 x 5 x 7 = 420 2 x 2 x 3 x 5 x 7 gives us a factor of 2... 2 x 2 x 3 x 5 x 7 and of 3... 2 x 2 x 3 x 5 x 7 and of 4... 2 x 2 x 3 x 5 x 7 and of 5... 2 x 2 x 3 x 5 x 7 and of 6... 2 x 2 x 3 x 5 x 7 and of 7.
2 x 7 = 14 2 x 3 x 7 = 42 2 x 7 x 7 = 98 2 x 3 x 7 x 7 = 294, the LCM
4900 = 2 x 2 x 5 x 5 x 7 x 7 or 22 x 52 x 72
x - 2 = 7 so x - 2 = 7 then convert that into an addition problem: 7 + 2 = x then add: 7 + 2 = 9 therefore x = 9
