3 (n + 7) = 16
The answer to this question is at my website aim feliciano980
the sum of 18 and a number equals 24
because the number are the same /example2 times 3 equals 6. 3 times 2 equals 6
(15+7) +99
0.5
It is the equation 9x + 6 = 4
It is the equation 6x + 2 = 4
the number is 11

n + 11n = 84
the sum of 18 and a number equals 24
because the number are the same /example2 times 3 equals 6. 3 times 2 equals 6
The sum of 45 and 15 equals 60. 15 x 3 equals 45.
4(n+12)
(15+7) +99
The equation for three times the sum of a number ( x ) and five times the number can be expressed as ( 3(x + 5x) = 36 ). Simplifying this gives ( 3(6x) = 36 ), or ( 18x = 36 ). To solve for ( x ), divide both sides by 18, resulting in ( x = 2 ).
