$5NN+10ND=450\\5(NN+2ND)=450 \\ NN+2ND=90 \\ \\ \boxed{NN=90-2ND} \\ \\ NN+ND=50 =>\boxed{NN=50-ND} \\ \\ \\ 90-2ND=50-ND \\ -2ND+ND=50-90 \\ -ND=-40 \\ \\ \boxed{ND=40} \\ \\ NN=50-ND \\ NN=50-40 \\ \\ \boxed{NN=10}$

How do I solve this

mojhsa [17]

GM = 1/2(GH)

7x + 2 = 1/2(32)

...multiply 1/2

7x + 2 = 16

...subtract 2

7x = 14

...divide 7

x = 2

GM = 7(2) + 2 = 16

MH = GM, so it is also 16
