Answer: 6g-2h when g=5 and h=4
and 2(g+1) when g=10 .
Step-by-step explanation:
1) 6g-2h
when g=5 and h=4, then we have
6(5)-2(4)=30-8=22
2) 20 g when g=2, we have
20(2)=40 ≠22
3) 2(g+1) when g=10 , we have
2(10+1)=2(11)=22
4) 4g+5h when g=1 and h=4, we have
4(1)+5(4)=4+20=21≠22
Hence, the required answer is : 6g-2h when g=5 and h=4
and 2(g+1) when g=10 .
