Step-by-step explanation:

3(3) - (-8)/4 = 9 + 2 = 11 so (3,-8) is solution
3(4) - 4/4 = 12 - 1 = 11 so (4,4) is solution
answer
C. both ordered airs are solutions
Answer:
8, 18 and 36 respectively.
<h2>explanation</h2>
sum=54
1st number=x
2nd number=x+10
3rd number =2(x+10)=2x+20
x+x+10+2x+20=54
put the liketerms together
x+x+2x=54-10-20
4x=24
divide both sides by 4 to get
x=8
Input the other values
French 156
Spanish 72
German 90
Italian 42
how we found out is by 360/60 to get 6 then 6 x 26 etc
