6n + 7n = 13n
6n + 7n (= 13n)
Your number is 6 7 * (6) - 5 = 37 3 * (6) + 19 = 37
It is 6 because: (6*7)+8 = 50
7x + 6 = 9x 6 = 2x x = 3
6 or -8
3 times 7 plus 6 is equal to 27.
18 is a solution to the equation 4 plus 7 times a number where the result is 9 times that number.
3x+6=x+202x=14x=7
5
The numbers are increasing in line with the 3 times (multiplication) table.6-7 is plus 1.7-10 is plus 3.10-16 is plus 6.16-25 is plus 9.Next in the 3 times table is 12. So, the next number will be 25 + 12.The answer is 37.
10 x 7 + 6 = 76
let the number be x. ∴ 6 + 4x = 7x ∴ 6 = 7x - 4x ∴ 6 = 3x ∴ x = 6/3 ∴ x = 2 Ans. The number is 2.
