Question 730862
Let x = score on each of the two games


The scores, 3,5,0,1,2,5,1,6,1,5,4,4,2 and the two additional scores (x and x) add up and divide by 15 (since there are 15 scores total...with the two x scores added on). This result is equal to 3.4


So this means...


(3+5+0+1+2+5+1+6+1+5+4+4+2+x+x)/15 = 3.4


(39+2x)/15 = 3.4


39+2x = 15*3.4


39+2x = 51


2x = 51-39


2x = 12


x = 12/2


x = 6


So they scored <font color="red">6 goals</font> for each of the next two games (6+6 = 12 goals for the next two games combined)
