0.5 m - 0.75 n = 16
Substitute n = 8 into the equation
0.5 m - ( 0.75 × 8 ) = 16
0.5 m - 6 = 16
( Add 6 to both sides )
0.5 m = 26
( Divide by 0.5 )
m = 52

Mean means to average. in order to average, add all the numbers then divide by how many numbers you have.
All these ages add up to 150. because there are 7 ages, divide by 7. this is 21.4 which can be rounded to about 21
46 + 48 + 21 + 12 + 15 + 8 = 150
150 ÷ 7= 21.4285 = 21
